Gustcloak Skirmisher

Block it and it slips away. The gustcloak trigger, the small white subtheme that handed the same blocked-condition to several Soldiers and Birds, takes ordinary combat math and quietly rewrites it. Normally an attacker commits the moment a blocker is declared: it deals and receives damage in that matchup, and the defender's creature is spent answering it. This one declines the fight. Once blocked, it untaps and steps out of combat before damage, which means the defending creature has tied itself up against nothing, and your attacker is back upright and ready to defend on the swing-back. The flying matters here in a specific way: only a flier or a creature with reach can block it at all, so the opponent has to spend their evasive defender to even put it in the gustcloak window, and then watch that defender accomplish nothing. The cost of all that is the body. A 2/3 for four is plain, and the ability is inert unless the opponent has both the bodies and the reason to block, which an aggressive shell can manufacture and a slow one cannot. What the design is really doing is taxing the defender's tempo without ever risking the attacker, a pressure tool built for a tribal deck that wants to keep poking and keep its threats alive, not for any abstract goodstuff slot.
