Welcome to Variable Power !

Hi there! Welcome to the primer of my Gruul Hydra, X-spell deck; commanded by Rosheen Meanderer. The Lorwyn Shadowmoor is home to a giantess shaman of considerable power. A collector of stories with a strong attunement to the weave. Every tale she hears she intuitively intertwines with ripples she experiences within the ocean of magic attuned to her very soul. This allows her to put into perspective all she hears with past-, present and even future events; shaping raw knowledge and feelings into prophecies. Her perspective however is so broad and all-encompassing, that almost nobody can understand her when she conveys this information. To most it would seem like the ramblings of a crazy being. Because of this, many tend to underestimate her. This is usually a very unwise thing to do, for there is a great deal of power in the knowledge she has access to. Power that seeps into her being from countless planes. When she chooses to manifest it, beings of unspeakable size and spells of indeterminate power spring to life and right now, they’ve all been brought to bear against you. This deck is meant to be played casually. It’s not meant to be used in a competitive fashion, but of course I welcome anyone to try! Feel free to comment on anything you (dis)like throughout this primer; I hope you will enjoy it!

Her mana ability is impressive; even if it can only be used to power x-spells. Her affiliation with the Gruul guild’s colors, grant me access to some of the most notorious, powerful x-spells in MTG’s existence. Additionally, this guild offers many avenues to increase/double mana amounts. That’s enough to lay the groundwork for an interesting deck-idea. Let’s not beat around the bush; Rosheen is also a capable combatant and has a reasonable casting cost.

I use the following ten parameters to determine the strength of the deck. For each, I allocate a score of 5 (very good), 4 (good), 3 (mediocre), 2 (bad) or 1 (very bad); when totalized this score represents the power rating of the deck (maximum score is 50 points).

  • Mana: indicates the availability of mana sources within the deck.
  • Ramp: indicates the speed at which mana sources within the deck can be made available.
  • Card Advantage: indicates availability of filter- and draw resources represented within the deck.
  • Overall speed: indicates the deck’s potential for pace, based on resource availability and mana curve.
  • Combo: indicates the measure of combo-orientation of the deck.
  • Army: indicates the deck’s creature-army strength.
  • Commander: indicates how much the deck is commander-oriented/dependent (less dependency is better).
  • Interaction: indicates how much this deck can mess with opponents’ board states and turn-phases.
  • Resilience: indicates whether the deck can prevent and take punches.
  • Spellpower: indicates the availability and strength of high-impact spells.

Mana: 5

Luckily, my commander is a fantastic mana-dork herself and due to her guild-affiliation she also has access to a choice cut of the best mana providers out there. Five additional dorks, four mana-doublers and five excellent mana-rocks provide additional energy-generation support. A number of the chosen cards have been added specifically because they’re more effective when applied to fueling X-spells.

Ramp: 3

When a deck features green (or white), land-fetching suddenly becomes a very feasible option to quickly increase my land-count. This deck features six such options; one of them actually generates lands instead of fetching them.

Card Advantage: 2

This game cannot be played very effectively unless once every so often, one gets the opportunity to draw some more cards than one per turn. So some cards have been included to grant that option; four direct draw-, three ETB/LTB draw and one tutor.

Overall speed: 4

As Rosheen usually makes her appearance by turn three, the deck’s X-spells will start to become effective during this time as well. No matter whether this involves angry looking hydras or devastating damage spells; the opposition will be in for a bad time. Before this happens however, there’s plenty of resourcing available that can be applied in many, simple ways that makes this deck’s speed above average.

Combo: 1

Just a few minor combos; nothing super significant.

Army: 3

Though this deck’s army is not particularly large, well over half its creature-power depends completely on +1/+1 counters. Thus the creatures we do put onto the field, have a chance of being (or becoming) extraordinary large and thereby powerful. The army also features some great utility functions including mana enhancement, artifact/enchantment destruction and life-gain.

Commander: 4

I really enjoy having Rosh on the battlefield, as the mana she provides is excellent and can be doubled easily within this deck (or even tripled in some cases). However, she’s not instrumental for victory perse as there’s more resources where she came from. However, she is dependable and especially during the early game grants me significant energy advantage over the opposition.

Interaction: 1

One of the deck’s weaknesses. It does have a few minor destruction options and some non-combat pinging, but that’s about it.

Resilience: 2

The deck doesn’t really feature much that provides staying-power. Mostly, it just focuses on dealing as much damage as I possible fast. It does contain some ways that prevent the opposition from countering spells, some hexproof, a bit of regeneration and even a little life-gain has been added.

Spellpower: 5

Heeeell yes! Spell-power galore! Obviously there’s a nice number of non-combat damage spells in here (twelve cards) along with some awesome mana doublers (three spells) and a smattering of others (including some decent destruction stuff).


Total power score: 30

Granted, this deck needs a little room to operate, which can be tricky as it doesn’t have that many defensive measures available. When it does have this room though, even a little bit, it can come at you hard with creatures and spells that will be tough to match by other decks. Its army is moderately sized but lethal and its spells are powerful damage dealers that in some cases can end games outright.

It’s pretty simple; gather oodles of mana-generating power and start breaking face with either powerful X-creatures (Hydras) OR damage-dealing spells. Use of the deck’s enchantments is important; give these priority in casting whenever you can as a number of these either double mana or greatly increase the deck’s damage-dealing potential. Be careful with the use of the deck’s permanent-removal options; it doesn’t have that many so only deal with opposing enchantments/artifacts that basically disable this deck or greatly empower an opponent’s deck.

At least three cards in the starting hand ought to be lands (or two lands and a cheap-to-cast rock like Arcane Signet or Sol Ring). This is a must; I’m not going to start a game without this hand (even if I have to mulligan down to three cards). The ideal hand would also contain some additional ramp and/or low-cost draw options.

First thing I want to is get my resourcing in order. In the ideal situation, I’ll therefore start with the casting of mana dorks like Birds of Paradise, Bloom Tender, Nexos and/or Selvala, Heart of the Wilds. Ramp spells like Exploration, Rampant Growth, and Three Visits will also be high on the priority list, as well as certain rocks like the ones mentioned in the previous section and Elementalist's Palette, which has tremendous generation potential. Early card-advantage opportunities will be jumped on as well. Cards like Colossal Majesty, Scroll Rack, Sensei's Divining Top and Sylvan Library will be cast as soon as I draw them. While all this goes on, I basically try to go Rosheen out as early as I can cast her, given the tremendous mana boost she gives me once present.

This phase starts as soon as it becomes beneficial to cast X-spells (the minimum requirement I usually put onto this, is being able to pump at least 6 into X; which will usually be available right after Rosheen enters the battlefield). In terms of X-spells that receive direct priority, are cards that either greatly expand my casting abilities OR that have a control aspect to them. Examples include Animist's Awakening, Apocalypse Hydra, Awaken the Woods an Steelbane Hydra. Next to these, priority is granted to spells that increase the size of my Hydras and the power of my X-spells in general. Favorites amongst these include Branching Evolution, Doubling Season, card:Fiery Eamncipation, Ozolith, the Shattered Spire and especially Unbound Flourishing, which seems to be almost tailor-made for this deck. Mana multiplication also helps on this front, in the form of Doubling Cube, Mana Flare, Mana Reflection and Nyxbloom Ancient. Once all this is present, other decks will be hard-pressed to match the sheer amount of mana I can pump into spells, allowing me to cast insane manifestations of creatures like Neverwinter Hydra, Ochre Jelly, Primordial Hydra or spells like Comet Storm, Crackle with Power, Fireball and Jaya's Immolating Inferno.

  • Ochre Jelly + Doubling Season: please … kill my Ochre Jelly! Season ensures that the Jelly won’t just return (as a token copy, but exactly as strong as when it died), but it will also generate an additional token; youch!

Reliable sources of mana, and some utility:

The cards I use to accelerate mana-availability:

  • Animist's Awakening: an X-spell that lets me top-deck lands, while redistributing other found cards to the bottom of my library; not a bad deal at all!
  • Arcane Signet: perhaps my favorite mana-rock next to Sol Ring; it’s cheap, versatile and easy to use.
  • Awaken the Woods: incredibly cool land-generation spell, provided I can keep the tokens it generates alive.
  • Birds of Paradise/Bloom Tender: being able to produce mana of any color with cards like these is such a treat!
  • Doubling Cube: once enough mana can be produced, this piece of artistry doubles it!
  • Elementalist's Palette: a very strong rock in this deck, as X-spells are cast on a regular basis.
  • Exploration: one of the best turn-1 ramp cards in EDH.
  • Kodama of the West Tree: most of the creatures in this deck can be considered modified, meaning I’ll be able to filter out my basic lands in no-time with this spirit around.
  • Mana Flare: I am fully aware that this wonderful spell drives up mana production across the table; but the chances of that impacting this deck in more ways than the decks of others are pretty good.
  • Mana Reflection: a stellar permanent for increasing mana production (though it’s such a shame that it doesn’t work with Neheb, the Eternal’s ability).
  • Neheb, the Eternal: in a damage-focused deck like this, it’s such an incredible powerhouse; the amount of mana he generates during the post-combat main phase is simply staggering sometimes.
  • Nature's Lore/Rampant Growth/Three Visits: amongst the cheapest tutors for (non-basic) Forests and other lands.
  • Nexos: turns my basic lands into excellent fuel-providers for X-spells.
  • Nyxbloom Ancient: a scary creature with an even scarier mana-multiplication ability that turns all my X-spells into annihilation-death-bombs.
  • Pyromancer's Goggles: a little red-mana that can double instants/sorceries.
  • Selvala, Heart of the Wilds: in a deck filled with insanely-powered creatures, this lady is one of the most welcome energy-sources that it can produce.
  • Sol Ring: (almost) no EDH-deck should leave its home without this card.
  • The Great Henge: mana resource, life gain, creature-enhancement and card-draw; all in one!

What I need in order to draw, scry or tutor:

  • Colossal Majesty: draw with a prerequisite that’s easily obtainable in a deck with creatures this strong.
  • Finale of Devastation: search for a win-condition, and then proceed with an empowered attack that deals at least an additional 10 damage per attacking creature (provided I pump it enough).
  • Lifeblood Hydra: whoever kills it, will probably ensure my victory by letting me draw any win-conditions I might need.
  • Scroll Rack: one of my all-time favorite EDH cards for increasing my options by extending my (virtual-)hand-size.
  • Sensei's Divining Top: perfect scrying card as well as a nice draw-enabler in a pinch.
  • Sylvan Library: draws me two possible additional cards, that could mean the difference between victory and defeat.
  • Worldly Tutor: great tutor that in some cases can capture some key creatures that enable victories.

Just don’t chop off the heads; it won’t work.

  • Gargos, Vicious Watcher: cheapens all other Hydra spells I’d like to cast, effectively making them bigger when they ETB.
  • Managorger Hydra: every spell allows him to grow; EVERY … SPELL! So unless someone gets rid of him, he’s going to grow big very, very fast.
  • Neverwinter Hydra: in a deck with as many mana-resources as this one, the potential of this creature becoming rather gigantic is huge.
  • Ochre Jelly: not exactly a Hydra, but obtains its strength in the same way and it’s very hard to kill if it managed to ETB with a large amount of counters.
  • Primordial Hydra/Voracious Hydra: double their counters on their own, very convenient.
  • Savageborn Hydra: strikes twice and can grow whenever I’ve got some spare mana.
  • Shivan Devastator: oh my, … a flying, hasty dragon hydra!
  • Stonecoil Serpent: not exactly a hydra either, but couldn’t pass it up to add it as the multi-colored protection is awesome in an EDH-setting.
  • Vastwood Hydra: it might die, … but its counters won’t!

Your life-total will be reduced by X.

  • Banefire: easy to make it uncounterable with this deck; not to mention deadly.
  • Burn from Within: an excellent X-spell that even helps to clear out those ridiculously powerful indestructible creatures.
  • Clan Defiance: a multi-functional damage spell that allows me to use all of its casting-varieties at no additional cost.
  • Comet Storm: there’s so much to love about this spell; it’s an instant, it costs next to nothing (1) to add an additional target to the spell and it deals X damage to all of them!
  • Crackle with Power: the value of this beauty cannot be overstated; especially in a deck with copious amounts of mana AND damage-doublers. Has finished off a multitude of games in my favor.
  • Electrodominance: multi-functional damage dealer with the added benefit of getting a free spell online.
  • Fireball: a classic that just has to be in here; especially useful as a targeted wipe in case I happen to need one; but useful against single targets as well.
  • Jaya's Immolating Inferno: can only cast this when there’s a legendary creature around; but that requirement is easy to fulfill and boy-oh-boy, does it deal some serious damage when it’s unleashed!
  • Red Sun's Zenith: a reusable X-damage spell? Sign me up!

Bits and bobs that helps out my games while undoing yours:

  • All Will Be One: with all the counters flying around, adding some damage to their appearance only made sense; it’s equally awesome to use as removal and against players.
  • Branching Evolution: doubling all my generated +1/+1’s.
  • Decimate/Hull Breach: every deck needs anti-artifact/enchantment spells.
  • Doubling Season: mostly in here for the counter-doubling, but it’s useful in some cases to double tokens as well.
  • Fiery Emancipation: the best damage multiplication.
  • Kalonian Hydra: every turn it attacks, hydras on my side of the battlefield double in size.
  • Lightning Greaves: superb protection for whatever creature I want to grant it to.
  • Ozolith, the Shattered Spire: even creatures without their own +1/+1 counters can get some with this artifact.
  • Steelbane Hydra: a repeatable artifact/enchantment remover at the cost of a counter and some mana; I’ll take it!
  • The Ozolith: counters will never be lost once this hits the field!
  • Unbound Flourishing: almost THE signature spell of the deck; empowers just about all the core cards it consists of.
  • Vexing Shusher: awesome utility creature in Gruul; especially when facing blue.
  • Xenagos, God of Revels: a divine upgrade for one of my hydras during each attack.

Currently not in here, for reasons described below.

  • Hungering Hydra/Protean Hydra: their ability to survive (and effectively grow stronger) after receiving non-lethal damage is intriguing for sure. However, opponents usually don’t risk damaging them and I find it a bit tedious to do so myself; especially since in every other way these creatures are vanilla that can be blocked by 1/1 chumps.
  • Hydra Broodmaster: was included in a previous iteration of this deck. It turned out to be a bit too slow for my liking at times, so I’m experimenting with some replacements at the moment.

I appreciate the time you took to read my primer. Hopefully it was entertaining and useful to you. If so, feel free to leave a +1 and/or feedback of any kind in the comments below. Thanks again!
