Cavern of Souls


As Cavern of Souls enters the battlefield, choose a creature type.

: Add .

: Add one mana of any colour. Spend this mana only to cast a creature spell of the chosen type, and that spell can't be countered.

How much are you keeping this deck up to date? I had a very similar inspiration, and the last few sets have added some interesting new toys. If you want to compare notes, mine's at Above such mortal concerns. (I did allow myself the luxury of Cavern of Souls, Voldaren Estate, and Blood Celebrant, so it's able to cast Edgar in a pinch, but the spirit's still there.)

How well do cards like Vampire of the Dire Moon and Changeling Outcast work for this deck?

A) Just another mana rock with sub-utility, acting as an equipment mid-to-late game.

B) Considered in the original decklist, however I've been favoring non-basic lands that offer side tech for the deck.

C) Not sure about this one. Nonbo with Abstruse Archaic and our own commander Kozilek, the Great Distortion.

D, E, F, G) Appreciate the thorough evaluation here of Chimil, the Inner Sun. Will play around your other suggestions against counterspells/interaction with Defense Grid and/or Cavern of Souls. For sure, I would consider these cards over Conqueror's Flail.

H) Noted! Might switch The Immortal Sun for Blinkmoth Urn.

I) Metalworker Very good card that ramps hard and can combo off with certain pieces in play. Current decklist runs pretty well without it due to the amount of fast mana, mana rocks, and cost reducers that are already in the deck.

  1. Got you, wasn't sure of intended power level but I saw some combos and thought you might want more. I will say, most people who do play against stax would prefer for that user to have combos to end the game rather than suffer. Nevertheless, noted.
  2. As above
  3. Expedition map could find you blinkmoth well which is nice.
  4. Great
  5. The combo is fun but yes, niche. But Karn himself is great. In EDH, people are bound to have lots of mana rocks. But if it isn't for you, I understand.
  6. Perfect swap

A) What is the purpose of The Irencrag?

B) Darksteel Citadel - Artifact count increase

C) Cursed Totem - Only anti-synergy with one card in your deck and can stop mana dorks and other pesky abilities. Pairs well with torpor orb.

D) Regarding your question if Chimil, the Inner Sun, I suppose it would depend on your meta's amount of blue players. My issue with it is that it, itself can be countered. My other issue is that sometimes there is a card thats 6cmc+ and you lose it because of it. It can produce some value for sure. If you're really worried about blue, then perhaps add some of the following....

E) Cavern of Souls - Easiest solution

F) Conqueror's Flail - Might not be the best but forces interaction pre-combat. Not just anti-blue either.

G) Defense Grid - The least impactful but easiest to use. You only have one instant and you don't need to equip anything.

Do be aware that they can still activate abilities, just not cast spells. Cursed totem could fix that of course, just worth mentioning. I love your numbering system, great job.

Other cards in your maybeboard worth including are....

H) Blinkmoth Urn - Synergy with blinkmoth well and will always put you ahead of everyone else.

I) Metalworker - Assuming this is due to $ or power limiting reasons?

Ah, that makes a lot of sense, very solid reasoning! Thank you for taking the time to explain it. I know you're budget, but perhaps a card to potentially consider for future acquisition would be Cavern of Souls? I know you generally want ulamog to die but it's nice to have the option to keep him around, can never be too careful against the blue player.

Speaking of lands and Ulamog dying, High Market and Miren, the Moaning Well might do you some good, particularly if theft is an issue. The latter has helped me against burn.

A few things.

1st off. I think a soul sisters deck and angel deck are not compatible. Soul sisters make and want as many lifegain triggers as possible. Maximizing cards like Voice of the Blessed . Angels i believe want to maintain x life above your starting life and gain in chunks of 5 for probably the best angel Resplendent Angel. These seem simular but that creates tough choices in deck design.

Book of Exalted Deeds with creature lands is a combo with Mutavault some decks just can't beat this.

I think you want the card draw off of Shelter but I personally think that card sux. You would likely be better with a green splash for just Collected Company or run a cheaper protection spell like Brave the Elements or a better card draw engine Welcoming Vampire perhaps.

Speaker of the Heavens is a suprise op card i have a angel deck on mtga for historic and it is a great agro card angels needed.

You are light in 1 key piece of any deck. Interaction.

March of Otherworldly Light is a favorite of mine.

Path to Exile could be decent

Dawn Charm niche counterspell/ protect a creature

Surge of Salvation protection vs opposing aggro

I'd suggest looking at another decks sideboard to help build a better one Check out decks like modern d&t or soul sister or angels and see what you want. But be sure to cover a few things.

Graveyard hate like Soul-Guide Lantern Something to fight control many different approachesCavern of Souls Thalia, Guardian of Thraben Artifact/enchantment hate Disenchant

And something for decks that you think you need more help with and expect to face. Perhaps a boardwipe for decks that go wide Doomskar or any other archetype/problem that needs fixing.

Apollo_Paladin on Warlock Life Drain

Kudos on a unique build, if nothing else. I have to say I'm kind of at a loss for any real suggestions as Warlock is such a strange tribal type to come across.

Really though, +1 for even giving it the effort, even if it is a bit all over the place. Maybe something like Icon of Ancestry could help you along? Also, Cavern of Souls is an excellent use of Mythic wildcards if this is indeed an Arena deck.

The only other things that spring to mind for suggestions would be other generic creature-type cards like Crippling Fear which could be a decent control card naming Warlock, Herald's Horn could be decent here, or even Vanquisher's Banner - but 5 mana with no real ramp in the deck can be a bit "yeesh", and Faceless Agent can be fun to play with should you lean real hard into the tribal archetype.

Either way, neat attempt here truly. Feel free to add me on Arena if you ever want to talk deck tech or run some test games. Info is on my profile here - good luck!

Goldberserkerdragon +1

Ancient Tomb - Ramp

Narset's Reversal - Versatile

Cavern of Souls - Against another blue player so you don't need to spend time recasting your commander or holding up counter magic to protect him.

Have you considered the Planeswalker version of Thassa Oracle? The name escapes me at the moment. Or is it's CMC too high for consideration?

Snuff Out and Force of Despair unfortunately work the opposite way of how we want; although they're cheap to cast in reality, their CMC is high, so they hurt us a lot to draw off Ad Nauseam. Cavern of Souls and Cabal Ritual are both solid options to proxy in for the cEDH sideboard, as they're both useful but way outside of what I'd actually spend money on. Defense Grid is in the middle sweet spot where it's not a super expensive card and I can see how it improves our combo; it probably limits the number of counterspells our opponent can hit us with while we're comboing off to two max, which is nice :)

Thank you for the suggestions!
