Day's Undoing

Sorcery

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

kingyfyvf on Grixis Wizard Commander Help

This is my first commander deck I got a few months back and have built it up slowly but am in dire need of help finishing it. I know it is slow and probably bad but I like it and it suits me just fine. I like how it can focus on the graveyard but the only strategies I have for it is the Duskmantle Guildmage and Mindcrank set and the Sphinx's Tutelage. Any help is appreciated.

Day's Undoing has some application, but Time Reversal doesn't end the turn. Given infinite money, Timetwister is the preferred card.

This deck I feel would much rather not shuffle the whole graveyard into it's deck. Stream of Consciousness works out pretty well in that way.

On another note, Exquisite Blood + Sanguine Bond combo would be the route this deck would take if it really did go with that, as both pieces are Replenishable.

Final point: Effects like Time Sieve have little application in this deck. Time Warp would be much better, as would most effects in that realm. Sacrificing 5 artifacts is almost back-breaking for this deck, and even with an Open the Vaults in hand, you's have wasted a turn using it, which defeats the whole purpose.

You cannot use Day's Undoing in a Nekusar deck. When Day's Undoing resolves, it ends the turn, exiling all spells and abilities on the stack--this includes Nekusar's and other cards' damage-dealing abilities. As such, you'll just wheel without damaging opponents.

Day's Undoing is a pretty nice wheel card

Here's a trolling idea, grab any 200 cards but don't play them, just keep them in hand. Next, find and play Battle of Wits, followed by Time Warp, and then Day's Undoing. Nothing says trolling like winning on turn 1 with battle of wits in a 60 card deck.

Kaleb_H99 on Wheel and Deal Nekusar, the Mindrazer

cdkime Thanks for the suggestions. I didn't put two and two together with Day's Undoing and the triggers not resolving so I'll definitely replace it with Library of Leng. I agree that with that card it will help me sort through my hand for the cards I need much better. I also like the idea of Lightning Greaves. I've noticed that once the deck starts taking off, Nekusar is targeted almost immediately. That extra protection will be key. I also will find a way to include Hive Mind and Forced Fruition. Hive Mind Will help a lot it building the effects, and Forced Fruition I can see how that could be disasters for me and for opponents so I'll have to be careful how I use it. With Phyresis, I'm going to have to think about using that one. I hate when I have to face an infect deck so I know I'll have a lot of salty people if I use it. Thanks again! This helped solve some issues I had run into while testing the deck out!

cdkime on Wheel and Deal Nekusar, the Mindrazer

Based on my own experiences with Nekusar, here's some suggestions:

  • Cut Day's Undoing. This spell is simply awful with Nekusar as it ends the turn while Nekusar's damage triggers are still on the stack. As such, the triggers are exiled and Nekusar will deal no damage.

  • Library of Leng is a fantastic card to run alongside Wheels. It allows you to discard the cards you don't want to keep, while redrawing your better cards.

  • Temple Bell is a deceptively bad card in a Nekusar deck. On paper, it seems like it should work--it's a free damage trigger each turn. In actuality, I've found it counterproductive. The hardest part of Nekusar is that your opponents are quickly cycling through their deck, so are quite likely to find the answers and removal they need. Nekusar works best with large, explosive plays that end the game as quickly as possible. Temple Bell provides no real utility on its own, requiring multiple damage-dealing cards or Mind Over Matter to function properly.

  • Nekusar is able to end games in fairly short order, so is usually a target for removal. Lightning Greaves would be a solid inclusion for some protection the turn he is played.

  • I've had some pretty good luck with Hive Mind in the past. One wheel effect is dangerous, but when multiple wheels are fired off simultaneously, the game ends.

  • Helm of the Ghastlord provides redundancy with Curiosity for your Niv-Mizzet combo. When placed on Nekusar, not only to you generate some impressive card draw, you also force your opponents to discard the cards they do manage to draw.

  • Forced Fruition is another game-ending spell, as it turns all your opponents' spells into forced draw. While giving opponents such huge card advantage can be problematic, it's fairly easy to hit for 14+ damage per spell they cast.

  • Phyresis can quickly end games with Neksuar, but will also ensure your meta hates you. It's worth considering, but might not be worth the ire you'll inevitably draw.

Onigma on Kefnet, The Handful

Kudos for building Kefnet Voltron, turning Kefnet sideways is the best! I have a few comments:

Have you ever thought about playing more timetwister effects to fill your hand? you already have time spiral and commit, there is also Time Reversal and Game Plan. If you want to dig deeper still there is also Day's Undoing and Diminishing Returns. It seems like you have enough permanents in your deck to play out your hand, so why not use those to refill your hand? Those incidentally also act as graveyard hate.

Also consider Inquisitor's Flail as a backup for Fireshrieker. Redundancy is never a bad thing.

Brass Squire is a easy way to equip Kefnet, especially if you have more untappers like Vizier of Tumbling Sands, Aphetto Alchemist, Voltaic Key and Fatestitcher

If you are going to consider Training Grounds, also consider Illusionist's Bracers. Again, redundancy is never a bad thing.

I have a considerably higher budget Kefnet Voltron deck Kefnet Savage Beaking (Multiplayer EDH). It might not be everyone's cup of tea but maybe you will find some ideas there that might interest you.
