Day's Undoing

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.)

Is Day's Undoing out of the budget?

yo! So to start, I can trade Jin-Gitaxias, Core Augur, Eldrazi Temple, Birds of Paradise, Arcanis the Omnipotent, Day's Undoing, which adds up to about $40. Looks like uro is $45 on tcg mid. I'd like to hold onto eldrazi conscription, c sphinx and breeding pool if possible because they are in decks right now. Anything else in the $5 range work for you?

Pikobyte I know, it is one of the cards I have thought of taking out for something else. I keep it in because it has helped me reset my hand at crucial times, but it does go against synergy. I'm actually planning on adding Neheb, Dreadhorde Champion so this will likely replace Day's Undoing

Day's Undoing doesn’t work with Xyris. It does give you a new hand but doesn’t produce any tokens!

I agree with almost everything Magnanimous suggested except Fevered Visions being a poor win condition. Sure, RDW can dump a bunch of burn on us. I'd suggest running a some main deck + some sideboard Swan Songs which would help with that + protect combo pieces vs control and has virtually no downside due to the fogs.

For Fateful Showdown I agree it's a little clunky. This card will sit dead in your hand most games and the double red is really taxing your 4 mana base with no fixing. I'd also consider cutting down on white, save for the Approach of the Second Sun which is easy to splash for at 7CMC. Repel the Abominable can be subbed out for Root Snare/Winds of Qal Sisma, Supreme Verdict for AEtherize which is easier on the mana and it can fill your opponent's hand back up for some Fevered Visions damage.

Also consider subbing out Growth Spiral+some of the fogs for Sylvan Caryatid/Anticipate. The caryatid can block some early aggression so you don't have to waste a fog early and will help with the mana base. Anticipate will help find that 3rd land drop, your combo piece or a fog when needed.

Shameless plug :D : check out my version of the deck running 3 color Day's Undoing, Sphinx's Tutelage, Jegantha, the Wellspring - Fevered Undoing Fog

Fog is Pioneer legal so it's a must run here.

Also consider trying Day's Undoing to guarantee the Fevered Visions damage much earlier and efficiently replenish on fog effects. Accidentally, it 's another enabler for Kefnet the Mindful although I don't think Kefnet is worth running as a 3 drop that doesn't have impact on the board or protect your combo.

For board wipe the added lifegain from Fumigate is not to be underestimated but ultimately Supreme Verdict being 1 less mana and uncounterable is too good to pass on.

Finally a shameless plug: please check out my Fevered Undoing Fog deck playing on this very concept as well as a Day's Undoing + Fevered Visions primer I've started - Fevered Undoing Primer

RNR_Gaming Thank you for pointing that out! I was stuck between Day's Undoing and Molten Psyche, and I thought I could get the triggers for the snakes the same way. My concern was to hit all graveyards to combat graveyard recursion decks. It seems counter productive in Xyris, though.

I like your list, too! Obviously, much more expensive lol, but I like your inclusion of Noxious Revival and Veil of Summer. Anvil of Bogardan is a spicy 2 drop that I didn't know about, and I will likely include that card in my updated list as well.

You may want to cut Day's Undoing. The reload is nice but you will not get any snakes.

  • If any abilities trigger while players are shuffling cards into their library or drawing seven cards, those abilities cease to exist when the turn ends. They won’t be put on the stack.

I built a more top end version; it might give you some more ideas but definitely think you have a solid start.
