Gustcloak Sentinel

The trick rewrites the combat math in the defender's head: declare a block, and this Soldier simply slips out of the fight, untapped and ready to swing again or hold back on defense. The opponent has burned a creature's combat step blocking air, and you have lost nothing. What pays for it is the strict trigger condition: the untap-and-remove fires only when this creature becomes blocked, so it does no work against an open opponent. It is purely a tax on their willingness to trade in the red zone, not a form of evasion. The "you may untap it" clause does double duty, since a creature pulled out of combat untapped is also a creature available to block on the crack-back, a quiet bit of vigilance-adjacent value bolted onto the escape hatch. The body is unglamorous, and the design is honest about what the cost buys: not raw power, but the ability to keep attacking into a board that should be able to stop you. This is the top end of a small white family of midsize attackers built around the same blocked-then-gone sleight of hand, an answer to a perennial design question about how to punish opponents for blocking without simply handing white the evasion it usually goes without.
