@iskelion: 1. Phalanxes are phalanxes regardless of equipment, but it's wrong to say that the effectiveness of phalanxes depend more on numbers than equipment. I am staying true to phalanxes as the actual military formation and what made it viable, not some trivially general definition of a category. Your logic can be used for why it's not dependent on numbers: the power of this card does scale to the number of creatures you have, like a phalanx formation should, because you have more creatures gaining HP.
@OdinVanguard: Okay, but that's only 1 deck that can be easily countered, and I've already conceded that the buff may be too powerful at +100%.
So I ask again, what about +25%?
