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

GoblinsBeatElves on Jace, MILLennial Archivist

Day's Undoing shuffles your GY back into your library. Here’s some ideas you could use: Fraying Sanity (and Traumatize is a combo with it Sanity out), Tome Scour, Hedron Crab, Jace's Phantasm. Also, drop Powerstone Shard. It’s not good enough for modern.

Day's Undoing is Timetwister for comp games.

Thanks for the response. What cuts would make to your list of you were playing in a non cedh environment?

Consecrated Sphinx, Glowrider, Tendershoot Dryad, Sunscape Familiar, Sun Titan, Elvish Spirit Guide, Glen Elendra Archmage, Glowrider, Lotus Cobra Loxodon Gatekeeper, Oracle of Mul Daya, Phyrexian Metamorph, Phyrexian Revoker, Day's Undoing, Idyllic Tutor, Fabricate, Timetwister, Windfall Frozen AEther, Grasp of Fate Kismet, Chalice of the Void and Lotus Petal are the cards not being played in the above mentioned list.

All the creatures with the exception of Loxodon Gatekeeper, Elvish Spirit Guide, Phyrexian Revoker and Glowrider seem like upgrades for a high end casual environment. If you could only include four creatures that are unique to your list for a casual list what would they be? My guess would be Sun Titan, Glen Elendra Archmage, Tendershoot Dryad, and Sunscape Familiar.

Idyllic Tutor seems really good in a midrange deck. Would its inclusion along with the widely played Enlightened Tutor allow for me to run Living Plane? Is Sterling Grove too slow even for a casual environment? Does Aura Shards make it back into the deck?

Day's Undoing is a bad card in a Nekusar deck - it ends the turn while Nekusar’s damage triggers are on the stack, so your opponents are not damaged as a result.

I would replace it with Niv-Mizzet, the Firemind. In addition to being a solid card in its own right, Niv-Mizzet provides you another near-infinite combo with Curiosity.

what I think this deck needs is 2x Countersquall and 1x Cyclonic Rift. Not quite sure where to fit them in though.

Maybe -1 Fatal Push, -1 Mana Leak and -1 something else? What do you guys think?

Draw really isn't the issue. Between the cantrips, Day's Undoing and Kefnet the Mindful itself, draw is covered.

Keep in mind that Day's Undoing does nothing for this deck. It contains the End Turn command. Any extra damage from being done with Nekusar will be skipped.

xyr0s on is Origins good for Modern ...

Joining the choir on this: Buy singles. Decide a style of deck you want, and start acquiring some of the pieces for it. Something like monowhite blink is fairly cheap to build, and can be gradually upgraded to death and taxes. On a narrow budget, you probably should forget about multicolored decks.

As for origins, there are a bunch of almost-good cards that could be used for brewing in a very budget-conscious meta (flipwalkers, Evolutionary Leap, Day's Undoing, and so on, but the probability of getting any of those in a fatpack is minimal. The probability of getting 2 of the same card is even minimaler, and you'll need multiples of cards you brew around for reasons of deck consistency.

ShikiTen on Draw-MATIC Effects

I love this deck. It reminds me of the early days of my Nekusar deck (which initially was going to have Lord of Tresserhorn as the commander before Nekusar, the Mindrazer showed up later that year). I am assuming you're on a more budgeted approach as some of the key Nekusar wheels that are more expensive are missing.

As for recommendations, I'll start by saying it might be easier to avoid cards like Psychic Spiral. While overall not a terrible effect, it's only useful if you play 1v1 or just need to finish someone off (which can be done with a massive similar effect). Here are some cuts I would make as well as what might be good replacements at similar or better mana costs:

  1. Psychic Spiral out for Time Reversal. - Effects everybody and still causes major pain from Nekusar.
  2. Laquatus's Creativity out for Wheel and Deal. - Slightly cheaper, hits all opponents, and replaces itself.
  3. Intellectual Offering out for Khorvath's Fury. - Choose everyone to be friend, & Nekusar causes pain. Also replaces itself with the added +1 draw.
  4. Day's Undoing out for Whirlpool Warrior. - Day's Undoing doesn't actually work with Nekusar because it ends the turn (removing all Nekusar's triggers on the stack). As an avid Nekusar player, this saddens me. If you don't like Whirlpool Warrior's enter the battlefield effect, Teferi's Puzzle Box is another great option. {Personally I would try to get both).
  5. Prophetic Prism out for Dimir Signet. - You have the other 2 signets for color fixing, why not get the third?

As for some other good-stuff cards you might want to look at: Magus of the Jar, Magus of the Wheel, Helm of Awakening, & Fellwar Stone are all possibile additions if you don't like some of the other suggestions.

Honestly, I am glad I found this deck because of a card YOU have in here that I need in mine. Kiora's Dismissal is great enchantment hate my deck needs as I regularly face against a G/W token deck with an enchantment sub-theme. Anyway, +1 from me on the deck!
