Just a quick round of casuals and some theory crafting leads me to believe this meta is really balanced. You don't have to agree with me or my meta assessment but I really like where the game is at right now. The amount of viable deck types is really staggering which puts me kind of at a loss.
Wind beats Earth.
Earth beats Water.
Water beats Lightning.
Lightning beats Void.
Void seems to do fairly well vs. everything but certain variations of lightning.
