I wanted to try something a bit different from my usual deckbuilding style, something that would be fun to play and would make for a decent deck to loan out to new EDH players. I've been wanting to build monoblack aggro for a while, but it needed some kind of twist to really hook people into the format when they played it. It also needed some kind of gimmick to distract them from realizing there are zero tutors, since nothing slows down the game more than the guy who casts Demonic Tutor and has to read 50 cards he's never seen before.
After sadly cutting Divinity of Pride and Deathbringer Liege from my Vish Kal deck and wishing I had somewhere else to play them, I knew I had my answer. Monoblack aggro...Reaper King.
