This card is... okay I guess. Nothing windmill-slam-worthy. but okay. There are no other +! power enchantments for 2 or less that don't have some sort of condition or requirement payment (see the better Gerrard's Battle Cry), so I guess it can get points there, however that doesn't make it good per se. In decks that run a lot of low toughness creatures (namely red decks), this is a bane rather than a boon. Still, it can be useful in the right deck. It's just that that deck type is very rare.
Pros: Universal buff for 2
Cons: Universal debuff for 2
