I love the deck. +1 from me. Since you had problems with finding a Decay, i would possibly drop a terminate for a decay? 3 MB is usually a good thing in modern as it is arguably the best removal in the format.

Also, i'm just curious, what's the Unravel the Aether in the SB for?

No. 3 Decays is not the place to be right now. It's a very good removal spell - just not well enough positioned right now. Unravel the Aether answers Keranos, God of Storms and Wurmcoil Engine. That are the main-targets - which otherwise Jund cannot beat.

I am also a big fan of Abbot and I believe he should be in the deck as more than a 1 of. But 4 feels very aggressive as he isn't really a two or a three drop and thus can slow down your deck immensely. The cards you cut aren't either but they are typically more powerful.

Your thoughts?

Abbot is great even on T3. If you're missing lands he's awesome, either he finds a land or exiles a spell you don't need anyways. And most of the time you have other things to cast and have him as back-up insurance. The prowess is super great against combo decks. Having 1 or even 2 Abbot on the board can add up to 4-5 prowess-damage over 2 turns. That's huge and often means -1 turn to kill. Abbot doesn't slow down the deck in the slightest, quite the contrary, he speeds up the deck a lot.

The list is now 10-2 in paper Magic. Last weekend I lost 1 match due to bad variance (played against D&T; and drew of 7 drawsteps 6 land and 1 Thoughtseize). The other games were won in very dominating fashion (UW-control, Merfolk, Twin (U/R and Tarmo) and Affinity). The deck feels super smooth. Couldn't be happier right now.
