Day's Undoing


Each player shuffles his or her hand and graveyard into his or her library, then draws seven cards. If it's your turn, end the turn. (Exile all spells and abilities on the stack, including this card. Discard down to your maximum hand size. Damage wears off, and "this turn" and "until end of turn" effects end.)

Day's Undoing Discussion

LeoSushi on Wanna hear a joke? "It resolves"

40 minutes ago

Mindbreak Trap is a quite good target for a wishboard, but is too narrow for me to consider without it, and $8 is a bit steep for the budget list,

Unsubstantiate is a decent tempo play, so I'll consider it

Day's Undoing is a good budget replacement for Time Spiral (a powerhouse in the nonbudget version of the deck) it definitely will find a home in the deck

Thanks for the suggestions enpc

Both Mindbreak Trap and Unsubstantiate are really good. They don't trigger Baral's ability but both of them do work. Also, since this a draw-go deck, Day's Undoing could be a really good option. While it nerfs a few cards, being able to reshuffle your graveyard can be really useful.

Reverie42 on K&T Tribal Card Draw

The most common Planar Bridge fetch I'd miss out on would be Curiosity for the Niv-Mizzet combo, but I'm not sure that's a really huge loss. I'm more suspicious that since most of the creatures in the deck are activated abilities or triggers rather than ETBs, a lot of pod activations won't feel like they're really gaining value.

AEtherspouts is definitely not really great. Cyclonic Rift would be way better. I'm hoping to pick one up a little cheaper at some point. Hour of Revelation is an interesting one. I had actually considered the similar Planar Cleansing, but ended up not running it because the idea of blowing up my own draw/tax effects seemed so bad. Too bad Austere Command is so expensive.

Praetor's Counsel is an interesting call. It would be good with both permanent sweepers and Birthing Pod. I considered Day's Undoing for a semi-similar role but haven't tested either on at all. Another good thing to think about.

Good stuff, thank you :)

I would recomend Paradox Engine, Mana Short, and Plagiarize. Mana Short, and Plagiarize along with enough mana and a untap engine allow you to lock all opponents out of cards, and mana. Plagiarize along with a card like Day's Undoing means that you can make one or more poeople get rid of their hands and you draw instead. I have been messing around with a Kaho, Minamo Historian too, and I feel these cards are very important to the deck. I also am thinking of running Fabricate, and Treasure Mage to find Paradox Engine. Training Grounds is also very good with Kaho, Minamo Historian.

derJ03 on Izzet a bird? Izzet a plane? No itz a Locust

Fiftyshotzlater I was actually thinking about adding Kozilek, Butcher of Truth but I wasn't sure if I need it with Time Reversal and Commit / Memory in combination with Mystic Retrieval and Recoup. But I will definitely think about it.

As for Laboratory Maniac: I couldn't test enough how realistic it is to draw that much, especially since I chose to not include the Skullclamp-Ashnod's Altar-Combo. But he is a hot candidate.

I'm not sure but the "end the turn and remove all abilities on the stack"-part of Day's Undoing also removes the Locust Gods trigger to create Locusts as far as I know.

And at last: I'm not a fan of Omniscience, Enter the Infinite and my playgroup is a bit weary about counterspells so Baral, Chief of Compliance doesn't fit that much.

Thanks for the suggestions. :)

Laboratory Maniac? Omniscience Enter the Infinite combo?could even throw in Baral, Chief of Compliance and some more counterspells for more of a control build. Day's Undoing or Kozilek, Butcher of Truth or Kozilek, the Great Distortion might be good too.

ASocialistCactus thank you so much for all your suggestion!

The thing about Frontier is that it is meta dependent. Top rated decks are usually Saheeli and Atarka, for sure. Like most builds, there are going to be flaws and/or strategies that just outpace whatever you may try to out forth. It's been well known that a combo deck like this is vastly outpaced to aggro builds, with the saving graces being the earlier interactions.

This ought to be an easy win versus midrange builds that will try and grind their way. Combo decks like Saheeli are tough and will probably be an even match depending on Saheeli's build.

It's difficult to come to terms with disassembling an entire deck strategy on the basis that I may or may not face creature heavy opponents. This was partly why I chose to have responses to those in the side. Locust God seems like a match made in heaven here, and Thing in the Ice seems decent, but flexible to other suggestions. The main philosophy as to why I chose a creatureless main is because it negates a lot of main deck removal and hate for creatures.

I didn't want to flood the deck with too many delvers, since it would hurt one of Jace's abilities. One thing I had thought of was perhaps Torrential Gearhulk for spell recursion and a decent body, Commit / Memory and Day's Undoing for more triggers.

Lastly, I had contemplated DTT, I'll never denounce its power as a card but since it doesn't help the gameplan in that it doesn't textually say "draw", I opted for Treasure Cruise. In any other control shell, I'm with you - DTT is just flat out better.

Thank you once again for all your thoughts and input! I'm happy that my build struck a chord with you!
