This is a PRELIMINARY mock up of a sweet UB deck I have been trying to conceptualize since Day's Undoing was printed. ALL SUGGESTIONS HIGHLY WELCOMED!
The core:The goal of the deck is to manipulate the element of card draw. We want to break parity whenever possible while cheating as much mana as we can. Efficiency is the name of the game, and recursion is an important part of the strategy.
Day's Undoing - This is the card that inspired the deck. Timetwister is part of the power nine, and this card is SOOO close to it. This deck aims to abuse it as much as possible.
Notion Thief - Since his ability is a replacement effect, it works exactly as you would want it to with Day's Undoing. Pay 3 mana, draw 14 cards is the definition of broken, yes?
Quicken - This card's interaction with Day's Undoing is BONKERS. I know it doesn't end the opponent's turn, but what it does is arguably better for the deck anyways. It lets me get Day's Undoing into my graveyard to be cast again! If Notion Thief is out, we are able to cast Quicken+Day's Undoing after they draw their card and they will have nothing in hand for their turn, while we sit happily at 14 cards to start ours. (Sadly the cantrip effect is lost since we have to shuffle that card into our deck with Day's Undoing's resolution).
Jace, Vryn's Prodigy
/Snapcaster Mage - We don't have very much controlling elements if you just look at our instant's and sorceries. These guys get us through what would be a rough middle game and make it a haven of selection and efficiency. Come late game, they are imperative in keeping our core synergies working until we close out the game.
Elements of control:All of our fun happens in the late game when we can manipulate and abuse our combos. To get there, we need to survive what would normally be a very weak early/mid game. To do that, we use the following cards to shape our victory early on.
Dismember - -5/-5 is enough to get rid of most threats in the format, and all early threats. The fact that we get to choose to pay 1, 2, or 3 mana for this makes it a flexible card that works insanely well with Snapcaster Mage. Instant speed, flexible removal is exactly where we want to be.
Negate/Spell Snare - We don't play very much counter magic. But the counter magic we do use HAS to be efficient. Negate is a catch all that stops combos, planeswalkers, and just about anything else that we couldn't normally deal with. Spell Snare is always a one mana tempo advantage that just so happens to hit the most common casting costs in our format.
Thoughtseize - I originally ran 4 of these until I experienced how bad it was in the late game. Turn 1, broken. Turn 7 when they have no cards in hand, its just dead. Its early game power more than makes up for its late game play. Pretty much a standard include in black decks across the board. (Considering using Inquisition of Kozilek to mitigate life loss).
Shadow of Doubt - My favorite land destruction spell. Costs 2 mana to destroy a land and cantrip? YES PLEASE! On the play, we can keep them on 1 mana for 4 or 5 turns with a perfect set of draws. Snapcaster LOVES this card, and once you hit your opponent with it once, they will live in fear.
Liliana of the Veil - Discard, removal, reusable. What more do I need to say? Oh, she has a fun ult too!
Win Conditions:How do we win the game once we have locked our opponent out of cards for the rest of the match? Well, the easiest way is to beat face of course!
Tasigur, the Golden Fang - Tasigur is too good to not include in this list. A 4/5 beater dodges bolt, and the fact that he has delve makes him even more insane. He gets rid of cards we don't want shuffled back into our library when we cast him, and as he sits in play, he generates SO MUCH advantage off of his ability. Did I mention he is a 4/5?
Creeping Tar Pit - Man land in our colors. Unblockable is a very nice bonus.
Notion Thief/Snapcaster Mage - These guys are small, but if we can keep our handle on the game, they can join Tasigur in beating our opponent's life to 0.
Utility - All decks need a bit of utility to push them over the top, this one is no different.
Minamo, School at Water's Edge - Great for extra looting with Jace, Vryn's Prodigy
. Can also double loot even with 5 cards in your graveyard with stacking the triggers correctly. Also, pseudo vigilance on Tasigur, the Golden Fang is great!
Oboro, Palace in the Clouds - Goblin Dark-Dwellers is a thing that is really annoying with
Bust
. Lets try to be protected as much as we can.
Reliquary Tower - we will be drawing a LOT of cards. I would personally like to keep them in my hand.
The sideboard definitely needs more work, and the mainboard is way open for discussion. Please let me know your thoughts on the deck!
