Black is a control/combo color in this cube and maintaining bodies to take advantage of the call of the ring card advantage is less than ideal.

What is a person to do with infinite mana? Probably go off with Retrofitter Foundry.

Will only be sticking with Premier man lands, creeping tar pit and one of the Azorius ones, haven't decided yet. Raging ravine is on the edge of being good enough. Threats are efficient enough that man lands rarely cut the mustard anymore.

1 Mana red damage that can hit opponents, rather than just permanents. Also, four damage from one card possibility, and hit two targets possibility.

White feels like its outstripping Red as the aggro color. Isamaru and Yoshimaru and Ocelot Pride are two super premium one drops, and outside of Ragavan and maybe Kellan the one drops in Red come with downside while the one drops in White all come with upside. White also has bonkers finishers like Armageddon x2.

I want to make sure Red Aggro has an identity that isn't 'White but less good', and I think that is Burn that hits the player and finishes the game.
