Caves of Koilos Discussion

SideBae on Aminatou in Progress

6 days ago
  1. So Preordain is awesome for the same reasons your Brainstorm and Ponder are... I suggest running it.

  2. Narset, Parter of Veils is a great way to limit your competitive opponents. Especially if you pair her with a well-timed Windfall . Ashiok, Dream Render happens to be another way to punish people for playing tutor-tribal kinds of strategies.

  3. Another hallmark of competitive decks is their ramp, especially zero and two-mana. In your description, you say you want to stay budget -- unfortunately, that rules out about all of the good zero mana ramp. ( Mox Tantalite is bad, and Mox Amber is hardly better most of the time.) So I suggest increasing your two-mana ramp, and maybe including Ancient Tomb if at all possible to speed up their presence on the board. Some to consider: Talisman of Progress , Talisman of Hierarchy , Talisman of Dominance , Coldsteel Heart , Fellwar Stone , Mind Stone , Everflowing Chalice , Prismatic Lens , etc. None of these should be more than a few bucks.

  4. Concerning your lands: I think you're running too many, especially if you add some of the ramp mentioned in (3). I'd cut four-ish, maybe five. Generally, once you have a few (3 - 4) lands, you'd rather have a rock and a land in hand than just two lands, since you can cast the rock without using your land-drop. I'm not sure HOW budget you want to keep this deck, but Mana Confluence and City of Brass are each around $10, and they're great in any three or more color deck. Pain lands ( Caves of Koilos , Adarkar Wastes and Underground River ) are better than your tapped lands like Sejiri Refuge , as far as I can tell.

  5. I think a reanimation package is probably better than running Show and Tell . Show and Tell is symmetrical, and is often actively dangerous to resolve in EDH, when everyone is trying to do busted stuff. I'm much more a fan of Buried Alive and Entomb to get your fatties in the bin, and then using Animate Dead , Dance of the Dead , Reanimate and/or Necromancy (which is $$$ for some reason) to get them back.

  6. Tutors like your Demonic Tutor are good, but like zero mana rocks they tend to be pricy (see Vampiric Tutor and Enlightened Tutor ). One I do suggest is Lim-Dul's Vault , which is only a couple dollars these days. It also happens to be instant speed, which is kinda dumb-powerful, if you ask me.

  7. Cumulative upkeep was designed to make powerful effects transient; however, Aminatou, the Fateshifter sorta changes that equation with her -1. Consider cards like Mystic Remora , which you can blink to keep around relatively indefinitely. Similar cards to consider are: Musician , Phyrexian Etchings , Tidal Control and Infernal Darkness (if you're particularly mean).

  8. Divining Witch is interesting -- I'd actually never seen that card before. If you're trying to exile your deck and win with your Jace, Wielder of Mysteries , I think Demonic Consultation is probably a better way... though you might want to keep both. Another method (that I think is worse) is to use the card Doomsday , which is only a few dollars. The problem is that if you run Doomsday , you'd likely want to run a Doomsday -package, so you could win by just casting it and drawing into your top card... For that, I'd suggest talking to someone smarter than me, as I've never been able to get the hang of what the hell is going on with that strategy. All I know is that the package usually has something like Gitaxian Probe and Lotus Petal and ends with me being dead.

  9. You may have good luck with card draw spells. Repeatable effects, like Phyrexian Arena and/or Dark Confidant , tend to be expensive; luckily, the spell versions are often decidedly less so. I suggest running a few or more of the following: Painful Truths , Night's Whisper , Treasure Cruise or Dig Through Time (running both can be tough since delve can get in its own way), Fact or Fiction , Thirst for Knowledge , Concentrate , Chemister's Insight , Oona's Grace (questionable, due to the high mana requirement), Ancient Excavation (good with the reanimation mentioned in (5)), Archmage's Charm , Chart a Course , Syphon Mind , Deep Analysis and/or Words of Wisdom -- pay extra attention to the instants you can cast on an opponents end step. Another way to do this is simply to steal your opponents' card draw with Notion Thief or Plagiarize .

  10. Lastly, I know its around $11 these days, but I think Counterbalance would be dumb in this deck. Using your general's +1 will let you stack whatever you want on top, which can be especially devastating if you can keep an opponent's general off the board that way.

Good luck man! Love this deck.

Caerwyn on Sorin to victory (orzhov vampires)

2 weeks ago

At the risk of sounding a bit rude, I don't think this has what it takes to be competitive in Modern, even considering it is a budget deck. Your deck currently has three major problems: (1) the mana base is unplayable in Modern; (2) your curve is way too high; and (3) a lack of viable interaction.

Let's talk about the mana base first. Lands that enter tapped effectively put you a turn behind and are, frankly, unplayable in Modern. We're talking about a format where games are often decided by turn 4--every single turn counts. I would promptly cut both Scoured Barrens and Forsaken Sanctuary and replace them with some combination of the budget-friendly lands of Caves of Koilos , Isolated Chapel , and Concealed Courtyard . That change alone should make for a drastic increase in your win-rate.

Next, let's talk about your curve. I think the following creatures are too low impact for how much they cost to cast:

  • Anowon, the Ruin Sage - This card just allows your opponents to sacrifice their worst creature. By the time you can cast Anowon, they almost certainty have something they can just pitch to the graveyard, so he is not really going to hinder your opponents any.

  • Sanguine Bond - for the reasons Kjartan already discussed.

Then you also have a large number of four drops--more than you probably need. I think it would be helpful to remove most of those, and focus instead on cards that make a huge difference the turn they're dropped. As I said above, Modern is often known as the "turn 4 format" - your turn 4 plays need to be explosive and have a large impact on the game.

Unfortunately, a number of the better vampires in Modern are not budget friendly (such as the exceptional Bloodghast ). Still, here's some to consider:

  • 4x Legion Lieutenant just gives a lot of value for two mana.
  • 4x Dusk Legion Zealot is a decent budget card, since it replaces itself in your hand.
  • 2x-3x Sanctum Seeker - this is solid, particularly if you add more cards that create vampire tokens. It does something the turn you play it, pinging your opponent for an additional 2-3+ life fairly easily.

I'd cut Sorin's Thirst and add Cast Down instead as a budget removal spell. It's going to hit most of what you want to kill and is a whole lot easier to hit in two colours than . 4x Fatal Push would be a strong upgrade, as it is one of the best removal spells in the game. Fatal Push has dropped in price some since it left Standard, so you might be able to pick up some relatively inexpensively. Eventually you'll want Path to Exile , but that's not the most budget-friendly card.

Since lands are colorless, you'll want to run the best lands you can afford, which usually means the fastest lands you can afford. Budget 3 color is difficult because the lands that are consistently the fastest also cost the most. A really handy resource for finding lands is All the lands in a sorted list. Just make sure what you find is use modern-legal. Typically, Scry lands like Temple of Silence are fairly affordable with a decent ability, but land prices vary depending on what colors they produce, so sometimes pain lands like Caves of Koilos or check lands like Dragonskull Summit are better priced. Another thing to consider regarding lands: either On Thin Ice or Chained to the Rocks - either could work with your colors, and both are powerful tools for only 1CMC. For example if Chained to Rocks were included, the best lands might be battle lands like Smoldering Marsh (because they have dual basic land types, ie: Swamp Mountain)

I also suggest Deflecting Palm in the sideboard - both as a defensive and offensive tool.

I'm not sure what your goals are here, but right now, you could add "Budget" to the decks hubs, which will increase the visibility a bit.

multimedia on Varina, Queen of the Damned

2 weeks ago

Hey, interesting version of Varina, but why only 21 Zombies?

DemMeowsephs has the right idea try to make all your sources of white and blue come from dual lands that can make black mana or fetch you black mana. Budget lands to consider adding:

Adding these dual lands can let you cut Plains and Islands for more Swamps. Or some could replace lackluster dual lands such as Tranquil Cove and Sejiri Refuge.

Zombies within the budget to consider adding:

Varina can gain you life which can make Command the Dreadhorde a powerful mass reanimation spell since it can also reanimate your opponents' creatures/Planeswalkers. Liliana, Death's Majesty is good for Zombies; all of her loyalty abilities are busted repeatable effects. It's helpful to play at least one Planeswalker if choosing to play Command the Dreadhorde.

Wonder and Filth can be good support since Varina is an enabler to get cards into your graveyard making these essentially free effects. Giving flying or Swampwalk to your Zombie horde can be game winning. Cut more Plains than Islands if choose to play Wonder.


Cards to consider cutting:

  • Tranquil Cove and Sejiri Refuge
  • Macabre Waltz
  • Cemetery Recruitment
  • Hedron Archive
  • Greed
  • Ever After
  • Geralf's Mindcrusher
  • Swiftfoot Boots
  • Graf Harvest
  • Fumigate

Good luck with your deck.

DemMeowsephs on Ghave, Guru of Good Stuff

Nice Deck, Abzan is one of the best tri colors for tokens, the only problem I can see regards the lands. I would consider adding some of the following lands: Godless Shrine , Temple Garden , Sunpetal Grove , Isolated Chapel , Silent Clearing , Concealed Courtyard , Marsh Flats , Fetid Heath , Caves of Koilos , Nurturing Peatland , Blooming Marsh , Llanowar Wastes , Verdant Catacombs , Twilight Mire , Scattered Groves , Razorverge Thicket , Canopy Vista , Brushland , Windswept Heath , Wooded Bastion , and possibly Prismatic Vista . Having these should help your deck out a lot! If you found any of these suggestions helpful I would appreciate it if you upvote my deck: A Deal With the Devil EDH! Nonetheless, I hope this helps, good luck on your deck, and have a nice day!

SideBae on Sharuum and the Artifacts

3 weeks ago

Hey! I always thought Shrauum was a cool commander, and I love that you're running Zur's Weirding (it's one of my favorite cards). Here're some suggestions -- feel free to ignore any/all of them:

  1. Xerox cards are your friend. Ponder and Preordain belong in pretty much any blue deck, as they can dig you to what you need and past what you don't. Being one mana means they make marginal opening sevens into acceptable hands. Similarly, Brainstorm is fully capable of being very good, though it requires more of a build-around. In order for it to be good, you need some cards to assure that you don't get Brainstorm -locked; that is, stuck with two cards you don't want on top of your library after resolving Brainstorm . The easiest way to deal with this is to simply crack a fetchland after resolution, as the shuffle-effect unlocks you. While the Onslaught and Zendikar fetches are the best for this, Evolving Wilds , Terramorphic Expanse , Prismatic Vista or even just Flood Plain or Bad River are good, too.

  2. Currently, Narset, Parter of Veils is one of the most busted cards in EDH. Preventing decks from drawing extra cards essentially means she is a 'must answer' before anything else can happen, and if you pair her with your Windfall you can win the card-advantage war in one fell swoop; this interaction is also favorable with your Dark Deal .

  3. Speaking of card-advantage, you are in the best colors for it. Fact or Fiction is a very good card, especially since you put the pile you don't choose into your graveyard. Since your general reanimates artifacts, this means the card is straight card-advantage. Treasure Cruise and Painful Truths are two draw-threes I've been very impressed with, mainly due to their frequently low casting cost. Dig Through Time is one that is good too, though I don't advise running it and Treasure Cruise at the same time, as delve can get in its own way. I think Treasure Cruise is better if you want to keep your combos secondary, and Dig Through Time , which provides more card selection and less card advantage, is good if you want your combos to take the front seat.

  4. As you mention in your description, your landbase can use some work. This, I think, is actually not as big a deal as one might think though, since you have a lot of very good two-mana mana-rocks that produce your colors. Still, if you're looking to improve the deck, this is an area with potential. If you end up running fetch lands, be they Onslaught, Zendikar or Slow (see (1)'s Flood Plain ), you should at least run the on-color shock lands. Godless Shrine , Hallowed Fountain and Watery Grave can all enter untapped, and being able to grab them with a fetch land means their odds of coming out in a game go up drastically. You may want to run them even sans fetches. Mana Confluence and City of Brass are good, as they are tri-lands that ETB untapped. The check lands (that is, Drowned Catacomb , Glacial Fortress and Isolated Chapel ) are only a few dollars now and offer consistent improvement. The pain lands ( Underground River , Adarkar Wastes and Caves of Koilos ) should also be considered.

  5. One card that I think you should test with is Bitter Ordeal . This IS a combo card, but I think it is likely better than most of the other ways to profit off infinite death/ETB triggers associated with your general + copying artifact combo. There are several reasons I say this. One, it is a sorcery. This means that, if you choose to run Mystical Tutor (which I suggest you do), it can find the payoff half of your combo; right now, this would only be true if you run Enlightened Tutor (I also advise this). Running an artifact/enchantment payoff to grab with Enlightened Tutor and another sorcery-based payoff to grab with Mystical Tutor means that you can tutor for a win-condition card off either of the tutors. Second, there are fewer answers to a sorcery than a permanent. Winning with Disciple of the Vault or Altar of the Brood requires that they stay on the field throughout the resolution of the combo; a well timed Abrupt Decay , Isolate or Swords to Plowshares / Nature's Claim means lights out. While Bitter Ordeal can be countered, so can the permanents; running Bitter Ordeal just means you narrow the number of possible answers your opponents can have. Third and finally, Bitter Ordeal is really only stopped by a Leyline of Sanctity effect. It is worth noting that there are ways that opponents can prevent being milled out by Altar of the Brood (like running Kozilek, Butcher of Truth and even benefit from it ( Tasigur, the Golden Fang or Whisper, Blood Liturgist come to mind), and ways that they can avoid dying to infinite drain ( Lich , Platinum Emperion and Platinum Angel come to mind). Again, Bitter Ordeal just limits the number of answers opponents can have.

Alright. That's all I got. Good luck!

CrimsonChaos on More cards being flagged

In my decks I'm showing Darkwater Catacombs , Boros Garrison , Cavern of Souls , Caves of Koilos , Dragonskull Summit , Evolving Wilds , Rakdos Carnarium , Sunbaked Canyon , Vault of the Archangel , Chromatic Lantern , Anointed Procession , Butcher of Malakir , and Cordial Vampire all as illegal in EDH. Also, the new cards from C19 have not yet been updated for legality, but since the official release is today that isn't terribly surprising.
