Background (unimportant): Hello there! I've been playing pauper on and off over the years at first very badly (mono green stompy without rancor) and a few months ago I built a fun UB faeries list that worked well for me. I like to brew, and after eventually discarding various fog/mill decks as unviable (somebody sided in 4x flaring pain wtf) I decided I wanted to try nonblue control. RW and BW control were okay, but I was eventually drawn to BR control due to the power of Terminate and Gurmag Angler.

The Deck: While I won't go in depth card by card, the deck is built on my (potentially wrong) assumption that Gurmag Angler is the best creature that you can play in pauper, and that decks that are not playing Gurmag Angler are secondary concerns. The removal suite is chosen to be able to kill Angler will still being flexible enough to clean up goblins or elves. The rest of the deck is card selection, a ported MBC Gray Merchent engine, and Anglers/Eldrazi Devastators to go over the top. The deck plays a very grindy game and is able to outlast almost every other deck, without significant early game weaknesses and retaining UB delvers ability to win off an early Angler.

I'm looking for advice mainly about decks that it appears my deck is unsuited to handle, superior sideboard options, or cards that I may have overlooked (I know many black decks nowadays play Oubliette), but also any comments you may have. I'm also interested in finding MTGO testing partners, to trade ideas with and tune brews. There's only so much you can get out of playing Izzet Blitz for the nintieth time. My MTGO username is Niched. Thanks for taking the time to read this post!

tl;dr: It's a BR Control deck. How can it be better?
