Allied Assault

The number that scales this pump is not creature count or mana spent but a deckbuilding audit: how many distinct party slots (Cleric, Rogue, Warrior, Wizard) you managed to field before casting it. That makes the card a payoff for a very particular constraint, one where filling four different class boxes matters more than raw board width. Get to a full party and you are handing out +4/+4 to a pair of attackers or blockers at instant speed, which is a genuine blowout in combat; assemble a partial party and the effect deflates in step, down to a dead card if you have no legal party members on the field at all. The design lives entirely on that variable X, and it splits the difference between a combat trick and a finisher depending on how deep you committed to the class-typing subtheme. The two-target clause is what elevates it past a doubled Giant Growth: one spell can turn two modest bodies into a lethal alpha strike or a two-for-one double block, but only for a deck built to feed the counter. It rewards the class-matters archetype specifically, and asks for nothing outside it.
