I like Balance-like cards because they really punish players who are running away with the game. Whilst this won't hurt, say, a token player as much as original Balance, it's a pretty solid substitute I think. Yeah, it costs double and doesn't specify permanent types but it can hit enchantments and artifacts so that's a bonus. Also, it's legal in all formats. That's a plus.
Pros: Balance that can force enchantment/artifact sacking
Cons: Doesn't force creature/land sack, costs twice as much as Balance
