Hada Freeblade
An empty body that grows itself: it arrives as a 0/1 that does nothing on offense, then accumulates a counter every time it or any other Ally hits the battlefield, including its own entrance. That self-trigger is the load-bearing detail. The first Ally you play under it counts itself, so even in isolation it stops being a do-nothing and becomes a 1/2, and the curve compounds from there: each subsequent Ally is another counter, retroactively pumping a body already in play. This is the Ally tribe's growth engine in its leanest form, the one-drop that turns a wide creature count into vertical pressure rather than just horizontal board presence. The design trades immediate value for a payoff that rewards committing to the tribe early: it offers the least when it resolves alone and the most in a deck dense enough to keep entering creatures every turn cycle. Unlike the Allies that grant a one-shot bonus on each enter trigger, this one banks the value permanently on a single creature, which makes it both the deck's best draw early and its most attractive removal target. The counters are real, so a single piece of spot removal erases an entire game's worth of accumulation, which is the tension that keeps the card from running away on its own.
