Post NA Eternal Weekend 2025 Legacy Championship
Here is the Entombsday decklist that I brough to the 2025 Eternal Weekend Championships. I did pretty well: I won 4 games and lost 2, but dropped before the 7th round due to starvation.
On each card, I've commented whether I was able to use it, whether it was ever dead, eetc.
Main Deck
My maindeck is a Tin Fins variant, heavily inspired by the writing on Doomsday.wiki. Going forwards, I want to do much more practice fishbowling the deck, then adjust things if I find that I can't reliable win game 1 quickly.
- ★★★★★: Joy to have in my deck.
- ★★★★☆: Almost always playable, sometimes let me down.
- ★★★☆☆: Playable, but situational. Maybe could be replaced by another option.
- ★★☆☆☆: Rarely Playable. See if it can be played more with practice, or whether its a dead card that should be replaced.
- ★☆☆☆☆: Horrible. Worse than a dead card, I had to play it and it lost me the game.
;4xBrainstorm#★★★★★. I loved using brainstorm to put Emrakul on top of my deck, then send it to the graveyard with Undercity Sewers. I underutilized it to see more relevant cards in conjunction with fetchlands. I need more practice.
;1xCabal Therapy#★★★☆☆. I used it to put Emrakul into the graveyard once. I never used it to send Griselbrand back to my graveyard. I need more practice recovering from whiffs where I have Griselbrand, but can't get Emrakul in play. I never entombed this, which I bet I could have. In general, I never played a discard card on my opponent once. I could have known much more about my opponent's ability to stop me. I could have killed my Thassa's Oracle...
;1xChain of Vapor#★★☆☆☆. I never once used this card. In Tin Fins, it is mainly to bounce one of my opponent's stax pieces or to return Emerakul / Griselbrand to my hand. It is simply unlikely that I'll ever draw it and in a fishbowl, I'd prefer to see Cabal Therapy or maybe another Goryo's vengance.
;1xChildren of Korlis#★★☆☆☆. I never used this card. I never entomb it / ressurect it, as why wouldn't I play Emrakul in that situation? I drew it at least once and maybe I won without it. I haven't had the experience of seeing it save the day yet. The Tundra I put into the deck to support it lost me many games where I needed a black mana!
;1xConsider#★★★★★. Fulfilled its role beautifully. Discarded creature from top deck, used it to win in Doomsday.
;4xDark Ritual#★★★★★.;
;3xDaze#★★★★★. Keeps my opponents honest. Single-handedly won me a game where my opponent comboed off to eagerly.
;1xEmrakul, the Aeons Torn#★★★★★. I was always happy to draw this. Unlike Griselbrand, it is much more deterministic in what it accomplishes. I'd like to try comboing with a retraced image or simply get better at using Griselbrand.;
;4xEntomb#Entomb did it's job well, but an entomb without a Shallow grave feels like a dead card, whereas a shallow grave always feels live, since I can get cards into the graveyar using Cabal Therapy / Consider / Undercity Sewers / etc. Without a shallow grave, even Lim-Dul's Vault seems more helpful. Also, I need to entomb Griselbrand in response to Chalice on 1 being played. I lost a game that way as I couldn't play entomb afterwards.;
;1xFlooded Strand#★★★★★;
;4xForce of Will#★★★★★;
;2xGoryo's Vengeance#★★★★★;
;2xGriselbrand#★★★★☆. I whiffed often enough, that I started to prefer ressurecting Emrakul as that has a larger immediate affect on my opponent. With more practice, this non-deterministic winner may go up in my estimation.
;1xIsland#★★★★☆. Helps me win Doomsday games against wasteland. Doesn't seem as helpful in Tin Fins, as it doesn't help with resurrections and Tin Fins isn't meant to pass-the-turn.
;1xLim-Dul's Vault#★★★★☆. Won me a few games. Also lost me a few games as it is slower than personal Tutor. If I could use it on turn 1 in Doomsday, that would be great! I feel like I would like more of it in Tin Fins as it topdecks Griselbrand / Emrakul and Undercity Sewers can immediately but that card in my graveyard or a cantrip can put it into my hand.
;1xLion's Eye Diamond#★★★★☆. My fast 1 mana pile hasn't been working that well. I also haven't found much use for it in Tin Fins. With more practice, I may find even more joy in this card.
;4xLotus Petal#★★★★☆. Great Card! Usually speeds me up by a turn, but it can be turned off in piles by Karn. One Eternal Weekend opponent even blindly played Chalice for 0, a billiant move that turned off a hand I kept with no land that would have otherwise been a turn 1 win. Unexpected!
;2xMarsh Flats#★★★☆☆. Always gets an Underground Sea. Failed me in situations where I wanted a basic island. If Tundra wasn't in this deck, then this would not be used.;
;1xPact of Negation#★★★★☆. I love this card, but a few people got me with consign to memory, which has replicate. Pact of Negation didn't help me in those situations. Maybe Flusterstorm or Mindbreak Trap may have been better.
;4xPolluted Delta#★★★★★
;4xPonder#★★★★☆. Usually when I see ponder in my opening hand, that means that I've drawn a slow hand with no gurantees. Therefore, I almost always mulligan hands with a ponder. It doesn't have instant speed like Brainstorm and I usually wish I'd draw a tutor or combo card. It is great for pitching to Force of Will, but so is Retraced Image or any other blue card I could put into the deck.
;4xShallow Grave#★★★★★;
;1xSwamp#★★★★★. Helpful against wasteland, good in Tin Fins, often usable in Doomsday, since a black mana is needed to cast Doomsday itself.;
;3xThoughtseize#★★★☆☆. I never played this card. I never tried to look at an opponent's hand. Perhaps I should have prioritized playing this on turn 1, rather than executing my combo as fast as possible. More practice may increase my opinion.
;1xTundra#★☆☆☆☆. Single-handidly lost me games where I needed black mana. I never once used the white mana in any of me games. Lotus petal can be used instead for white mana if needed. Replace this with Underground Sea x 4 or a Badlands. I'd prefer to keep this deck perfectly {U}{B}.
;1xUndercity Sewers#★★★★★. MVP! This card lets me do losts of cool stuff. I could have used it better to maximize the relevant cards that I saw.;
;3xUnderground Sea#★★★★★. Perfect! I wish I had had room for 4 of them in the deck. Weak to Wasteland however.
Side Board
;1xCavern of Souls#★★★★☆. Did its job of protecting vs. counterspells. Failed against Consign to memory.
;1xDeep Analysis#★★★☆☆. I tried to use it. Maybe I succeeded a few times. It allows me to win fast, but in an unprotected manner. I may be able to free up space by removing my 1 mana combo from the deck.
;4xDoomsday#★★★★★.
;1xEchoing Truth#★★★☆☆. I never played it.
;1xEdge of Autumn#★★★☆☆. Great in single turn kills, failed me in games where I needed to slow down and execute my pile over multiple turns.
;1xIdeas Unbound#★★★☆☆. I want to use this more. Also, there was one game where I used just to draw cards and I forgot its trigger. Oh Dear!!
;2xLim-Dul's Vault#(See comments for this card in Main Deck)
;2xStreet Wraith#★★★★★
;2xThassa's Oracle#★★★★☆. I lost at least twice to Consign in memory, which counters its ETB effect.
What I wished I had in my deck.
;1xChrome Mox#At least once, I whiffed due to a lack of mana. Having a Chrome Mox may have helped me. It seems like a way of further speeding up my combo.
;1xUnderground Sea#Whenever I saw that Tundra, I wish it had been an Underground Sea.
;1xCollective Brutality#There was one Tin Fins game where I could have cast Pact of Negation on my opponent's turn and won the game at instant speed thru a loop, but I had no way of causing life loss outside of combat as I didn't have a copy of Collective Brutality in my deck.
What beat me?
I'd like to be able to win without passing the turn.
;1xDisruptor Flute#I played an awesome lands deck.
;1xEndurance;
;1xWasteland;
;Consign to Memory;
;Force of Will;
;Grindstone#I was too busy hoping they wouldn't combo that I forgot again that this card can clobber me.
Pile to beat Consign to Memory.
;Consign to Memory#Beat me twice. Once, I wasn't expecting it and another time, I forgot that it had replicate.;
{U}{U}{B}: Draw Cards + Entomb + Unearth Lab Maniac + PTT.
;Ideas Unbound;
;Dark Ritual;
;Entomb;
;Unearth;
;Laboratory Maniac;
This pile provides perfect defense against consign from memory specifically.
{1}{U}{B} + 4 Life: Predict, Unearth, Draw cards to win the game.
;Predict;
;Laboratory Maniac;
;Unearth;
;Street Wraith;
;Street Wraith;
{1}{U} + 2 Life + PTT: Predict, Petal, Unearth, PTT, Cycle Street Wraith to win.
;Predict;
;Laboratory Maniac;
;Unearth;
;Lotus Petal;
;Street Wraith;
This pile tries to win two times. I'm not enamored with it.
{1}{U} + Predict, Petal, Unearth (Win?), PTT, Cast Thassa's Oracle (Win!)
;Predict;
;Thassa's Oracle;
;Lotus Petal;
;Unearth;
;Thassa's Oracle;
{U}{U}{B} + We know that Consign to memory is in opponent's hand. This pile can be adapted to include any proactive card in place of cabal therapy. Maybe a Veil of Summer?
Ideas Unbound, Cabal Therapy (Naming Consign to Memory), Lion's Eye Diamond + Street Wraith, Thassa's Oracle.
;Ideas Unbound;
;Cabal Therapy;
;Lion's Eye Diamond;
;Street Wraith;
;Thassa's Oracle;
Try to win twice. (Similar to Grindstone Defense.)
{U}{U}
;Street Wraith;
;Street Wraith;
;Thassa's Oracle;
;Edge of Autumn;
;Thassa's Oracle;
Notes: Veil of Summer doesn't stop Consign in Memory at all. Flusterstorm only stops the copies, pact of negation only stops the original. To deal with it, we need to try to win twice, use Lab Maniac, or discard it form the enemy hand.
Pile to beat Lands: Disruptor Flute + Endurance + Wasteland.
;1xDisruptor Flute#I played an awesome lands deck.
;1xEndurance;
;1xWasteland;
Let's assume that its my turn pre-doomsday with the ability to cast Doomsday. I don't have a free cycle effect, so I must make a Pass-The-Turn pile.
I have these mana resources:
;1xSwamp#Can't Produce Blue.
;1xUnderground Sea#This will die to Wasteland.
;1xLotus Petal#Won't be after Doomsday.
Here is an attempt at solving this puzzle.
Disruptor Flute:
- Counter it.
- Two win conditions.
- Win before it is played
- Need to remove it from battlefield.
- Get 3 extra mana.
Endurance:
- Play at most (0)! non-permanent spells, because Wasteland will send Underground Sea to graveyard. Underground Sea + Doomsday itself is the limit.
- Up my devotion to blue.
- Remove cards from my deck / graveyard.
Wasteland. This is going to remove my ability to cast blue next turn. It would have been better if that swamp were an Underground Sea in my past game where this situation showed up.
- I can't do anything to stop this.
We can win in 5 Turns.
Here is a pile that is guaranteed to win, but must pass 5 times and the opponent will probably draw more disruption by then. This is a very tough situation and it may be best to simply avoid casting Doomsday until we've dealt with more of their disruptive elements. It took me a lot of thinking to imagine a pile that beats Wasteland + Disruptor Flute + Endurance.
;Cabal Therapy#Removes Endurance or forces it to be played. If it is played, then we will have 6 cards in our deck: [US, US, TO, DR, DD/US, DD/US, we'll need to pass another 4 turns.
;Underground Sea#Gives us {U}.
;Underground Sea#Gives us {U}.
;Thassa's Oracle#Wins the game when cast with library of size ≤ 2.
;Dark Ritual#Combined with the original swamp, it allows us to bypass Disruptor Flute;
We can win in 4 Turns.
