Well mono black agroo looks like a good bet for the next meta. This guy can trade with a low curve creature, exile it and make a 2/2, you lose 1 power overall but will have the token, also vs chump block you just keep getting more power on the battlefield. 10/10 design.
In what universe? If you build a deck like that, and ever draw that hand, I will personally come to wherever you live, perform complicated acts of awestruck ********, then disembowel myself to escape the world that allowed something like this to occur and validate you.
