MagicalHacker on Rosheen Meanderer Hydra Disco

3 days ago

In terms of ramp, most of the ramp you have are cards that push you only 1 mana ahead, which I think is too small of an effect unless it comes with another valuable effect. Because of this, I would drop Mina and Denn, Wildborn, Sakura-Tribe Elder, Rampant Growth, Animist's Awakening, and Gruul Signet for Worn Powerstone, Astral Cornucopia, Gyre Sage, Khalni Heart Expedition, and Overgrowth. That kind of upgrade to your ramp will ensure that you get huge creatures out very easily. If you want to see other cards that could also fit this role, check out MagicalHacker - List of All Ramp Cards, but I would say that this deck definitely needs cards that advance your manabase by two or more, so ignore the cards that only ramp you by one.

Secondly, I only see three cards in here for draw, so there's no wonder that this deck doesn't hold it's own! We have all been there at some point, so let me emphasize this point: Draw is the most important thing for 99% of decks. Draw will let you have options, draw will let you build board states quickly, and draw will make it harder for you to get mana screwed or mana flooded. All of these are very important. You have Harmonize, Lifeblood Hydra, and Citanul Flute, but let's try to get 7 more cards for draw in here. If you need to take some out after testing, that's fine, but I don't see that being a problem. Too much draw isn't usually a problem with 10 cards that draw in the deck, so I think you should add any 7 of the following 9 options: Abzan Beastmaster, Elemental Bond, Triumph of Ferocity, Drumhunter, Outpost Siege, Lifecrafter's Bestiary, Skullclamp, Wheel of Fortune, and Life's Legacy to your deck to be able to refill your hand quickly and often. Check out MagicalHacker - List of All Draw Cards (Steady) and MagicalHacker - List of All Draw Cards (Burst) if you want to see options I didn't mention or options that aren't quite so expensive. I do think that those 9 cards are probably the best draw cards for your deck though, so picking 7 will bring your draw up to a reasonable amount. (I'll get into what 7 cards to drop soon.)

Next, let's tackle boardwipes. You've got Savage Twister and Chandra's Ignition, which I think are fantastic, but you do need more. There are only a few board wipes that can kill flying creatures and nonflying creatures in red and green at a reasonable mana investment, and those are Nevinyrral's Disk, Chain Reaction, Heaven / Earth, Blasphemous Act, Rolling Earthquake, and Starstorm. I think you can pick any 3 of those to add to the deck and you will be set on board wipes. (This brings us up to 12 cards that need to be dropped.) If you want even more options, again, feel free to check out MagicalHacker - List of All Board Wipe Cards to see more cards that could work, but I think adding any three of the above options would be fine.

Now, let's move on to item removal. You have Decimate, Hull Breach, Vandalblast, Beast Within, and Steel Hellkite. These are all fantastic, but I'd like to see Chaos Warp as well to be able to deal with any permanent.

Lastly, let's take a look at what cards you have to be able to deal with creatures at instant speed. Most people assume that dealing with creatures at sorcery speed is just as strong as dealing with creatures at instant speed, but here is why that is not correct: your opponents' creatures are good cards for you when they are attacking other opponents, and they only become problems when they attack you. For that reason, it's important to remember to have lots of instant speed removal to be able to kill creatures during combat when they would deal lots of damage to you or to kill creatures that are about to allow an opponent to go infinite. That said, your only options for that are Chaos Warp and Beast Within, making Chaos Warp that much more important for this deck.

Now that we have gotten the enablers down, let's talk about the bulk of the deck. To really abuse Rosheen Meanderer, we want the rest of the deck to be about using that X restriction. That said, we do want to use cards that will use that restriction to do things of value. If we are going to make big creatures (which we do want to do), we want to make sure that those creatures can attack to deal damage to players by giving them evasion.

Lifeblood Hydra and Primordial Hydra are the only ones that have an evasion ability naturally, so then we are forced to include things to give evasion. Flying is a good start, so I think that Akroma's Memorial and Homura, Human Ascendant are a place to start. You were right to add some ways to give everything trample, but I would add Khenra Charioteer, Gruul War Plow, and Primal Rage. Those five in addition to your Nylea, God of the Hunt and Archetype of Aggression should be enough ways to make your big dudes go through.

I realize now though that I've lost track of how many cards to add, so instead I am going to make a decklist to show what I would suggest this deck should become. No worries, I will link it at the end.

I would actually add all the creatures that cost X but enter with X counters (excluding the ones that cost double X, since those are not as powerful). And after that, just some ways to double +1/+1 counters or use Rosheen's ability will round out the deck.

Personally, I believe that 37 lands including Sol Ring would be enough since you now have enough ramp, so I brought down the number of lands too.

Hope I was able to help you!

SpaghettiToastBook on Ashling the burn deck

4 days ago

Chain Reaction is a really good board wipe: it's inexpensive, has a low CMC, and almost always kills everything.Staff of Nin is recurring card draw and it's cheap. Mind's Eye is more expensive but probably better at drawing cards. Magus of the Wheel and Dragon Mage are more wheel effects you could try. You might also want to try Mana Flare, Treasonous Ogre, or Caged Sun for even more mana to sink into Ashling.

You might want to try damage doublers: Furnace of Rath, Insult / Injury, Quest for Pure Flame, Dictate of the Twin Gods, Curse of Bloodletting, Gratuitous Violence, or Overblaze. All of these are pretty inexpensive.

Copying spells is a neat way to increase the value of your burns. You could try any of these: Reverberate, Wild Ricochet, Fork, Chandra, the Firebrand, Dual Casting, Dualcaster Mage, Increasing Vengeance, Howl of the Horde. You can also use most of these to copy pesky counterspells or copy draw or ramp spells. Price of Glory is great since you're mostly playing at sorcery speed. Pyroblast, Red Elemental Blast, Ricochet Trap, and Burnout are good for hating on blue players. Overmaster, Reroute, or Shunt might be okay too.

sparkblazewarriors on Wait, whose card was this again?

1 week ago

I play this commander as well, great fun. More redundancy with the threaten effect is quite nice with Conquering Manticore and Molten Primordial for when Yasova has been killed too much and also leaves you another big body. Cyclonic Rift is just too good not to include in most any commander deck with blue. On that line of thinking, more boardwipes is always a welcome addition for when you fall behind, stuff like Blasphemous Act and Chain Reaction which are more reliable than Bonfire of the Damned for killing a large amount of creatures. More card draw is also a must in this deck to keep your hand fueled, things like Prime Speaker Zegana and Rishkar's Expertise have been all stars in my build, Zegana also can get nuts with Conjurer's Closet or Deadeye Navigator.

I do caution against Hydras as wincons, they mostly just durdle about and get chumped while stuff like Molten and Diluvian Primordial can have a big impact when they hit the field. Also, I've found Yasova to be very mana hungry when using her effect so it's hard to justify saving mana for just a big hydra that doesn't have immediate impact on the game. Scourge of Scola Vale is ok because it gives you a sac outlet and Genesis Hydra can potentially dig for a good card, but the other two don't offer much. Hydra Broodmaster does nothing when it hits the field and requires a lot of mana to be effective and in the same vain Hooded Hydra is mostly just a big beater that can be chumped. Big beaters in commander really need to do something else besides attack as otherwise an opponent with a Path to Exile just removes your hydra before you get anything out of it, on the other-hand Primordials will give you their effect when they hit the field still. If the deck can easily generate infinite mana, then it may be a different story since Hydra Broodmaster with infinite mana is ridiculous, but I don't see how you do that very easily.

Hope this helps, feel free to disregard my wall of text.

Chain Reaction, Blasphemous Act, Wash Out, and Cyclonic Rift will all serve you better than creatures to block with. Reds spot removal isn't great in EDH, but Chaos Warp is solid. Blue has stuff like Reality Shift, Ovinize, and Pongify that will help.

No. Mass reanimation is not in these colors. But there are a few good cards for one or two creatures at a time.

Most important inclusion is Mana Echoes

TheDarkSlayer21 on marchesa budget +1+1 counter deck

2 weeks ago

I realize that you have a budget for this deck, but I will let you be the person to decide what is too expensive and what isn't.

With that said, there are typically two ways of making a Marchesa deck. The first way is to put in a lot of creatures that can get +1/+1 counters easily (Cards like: Anthroplasm, Aetherborn Marauder, Butcher Ghoul, Carrion Feeder or Unleash/Modular cards). The problem is, these cards hardly do anything other than putting counters on themselves. Their pretty much duds. So to make up for this, people will put in good sac outlets, (Cards like: Mind Slash, Phyrexian Altar, Ashnod's Altar, Altar of Dementia, Attrition, etc.) This type of deck gets its engine running STRICTLY from it's sac outlets, (NOT FROM ITS CREATURES) and because of this, it is a bit more reliant on its commander.

The second type of deck is my preferred method of playstyle. Whereby, the deck is not RELYING on its sac outlets, (although it does have a few) but rather on the ETB/graveyard triggers of creatures (Cards like: Mulldrifter and Harvester of Souls). With this type of deck, you're also not fully relying on your commander. Marchesa is just a perk. If you don't have her out, you can still play your creatures and benefit from them.

Also keep in mind, that it isn't too hard getting +1/+1 counters on your creatures just using the dethrone ability itself. I find that most, if not all the time, you will NOT be at the highest life total; especially if you have Necropotence, Ancient Tomb, Unspeakable Symbol, shock lands, fetch lands, and pain lands in the deck.

This is the Marchesa deck that I personally made. You're welcome to look at it for suggestions.


Commander / EDH TheDarkSlayer21


Some cards that I would highly recommend putting in the deck are:
- Unspeakable Symbol
- Sneak Attack
- Rune-Scarred Demon
- Demonic Tutor
- Necropotence
- Consecrated Sphinx
-River Kelpie
- Diabolic Intent
- Flayer of the Hatebound
- Glen Elendra Archmage
- Mind Slash
- Thalakos Deceiver
- Phyrexian Tower
- Cyclonic Rift
- Scourge of the Throne
- Dack's Duplicate
- Mikaeus, the Unhallowed
- Grimgrin, Corpse-Born
NOTE: If you do decide to have this deck be a bit more ETB heavy, Deadeye Navigator and Rite of Replication are good cards to help abuse the ETB triggers. And again, I acknowledge that many of these cards are pretty high in price, so I will leave it up to you to determine what's too expensive.

P.S. I would take out Endless One. If it dies and comes back, it will be a 0/0. So it's useless for this type of deck. Also, if you're searching for other Board Wipes that are as good as Damnation, I would recommend Blasphemous Act, Chain Reaction, or Decree of Pain.

TheDarkSlayer21 on Maleficent

3 weeks ago

I have been thinking about Panharmonicon for a very long time, and I think that the ETB cards are just not consistent enough to have it be completely beneficial. I would prefer to have at least 15-20 ETB cards if I were to include that card.

And while Insurrection is a phenomenal card, I only have three sac outlets in the deck. (Phyrexian Tower, Mind Slash, and Grimgrin, Corpse-Born. And only Grimgrin lets me sac as many creatures as I want for free.) So to effectively pull off an insurrection combo, I would need to have enough mana to play both Insurrection AND a Board Wipe. And all of my Board Wipes cost between 4-8 mana to cast. That would require me to have at least 12-16 mana at one time. So most of the time people would just get their creatures back.

I have also thought about putting in Blasphemous Act. I actually like that card a lot. But I think I have worked out a nice balance whereby I have enough Board Wipes in the deck. The only Board Wipes I would consider replacing are Chain Reaction, and Life's Finale. And I like Chain Reaction because it is consistently cheap to cast. And I like Life's Finale because it can put powerful creatures in graveyards for me to steal/get rid of.
