Winter Soldier, Reborn Avenger

The reanimation clause here is gated on power rather than a fixed mana threshold, and that scaling is the whole engineering problem. A base 3 power means the attack trigger starts by reaching creatures of mana value 3 or less, but every anthem, every counter, every combat buff pushes the ceiling upward: the more you can grow this card itself, the deeper into the graveyard each swing digs. White has always been the color of reanimation-by-restriction, capping its recursion with a small size window and paying for the effect with that cap. This design swaps a printed number for a moving one, which turns deckbuilding into a question of how aggressively you can scale the attacker's power before the graveyard has anything worth returning. The 3/5 body is built to survive combat and keep swinging, since the ability only fires on attack and only recurs one card per swing; the toughness is what lets it attack into open boards turn after turn rather than trading and shutting the engine off. It rewards a graveyard stocked with a curve of creatures rather than one fat target, because you get repeated small returns, not a single blowout. The Hero counter reveals what the card was assembled to headline: a Hero-typed toolbox where the returned Hero comes back a touch bigger than it left, a persistent buff on that creature rather than any feedback into the reanimation math, which cares only about this card's own power.
