Okay, 1 is good. Or at least, the premise is sound. r/g beatdown with black for effective removal is an old strategy, but planeshift makes it REALLY GOOD. tuning can always be added, but the idea is solid

# 2 is weaker. The best way to win with this deck would be to throw in white with a couple wraths. Discard to force them to overcommit, then mass destruction to punish them for it.
