Trusted Pegasus

Evasion-granting on attack is a familiar white trick, but most of it lives on instants and enchantment auras; stapling it to a body that attacks under its own power changes the math. The trigger fires only when this creature attacks, so the flying it hands out is tied to the same combat step it commits to, and it can only lift a fellow attacker off the ground: no defensive use, no ambushing a blocker, no holding it back as a combat trick. That restriction is what keeps a repeatable evasion engine from tipping into oppressive: it wants to be the aggressor, and it can only ever help another aggressor. What it enables is a ground-pounder punch. A wide board of nonflyers stalls against any competent defense, and this reroutes one of them over the top each turn it swings, turning a stalled attacker into damage the opponent has to answer in the air. The pegasus is a modest flyer itself, so the reward grows with whatever it partners: the bigger the grounded creature you send skyward, the more the three-mana body justifies its slot. It reads as a sponsor rather than a threat, a creature whose own attack step exists to set up a better one, and the deckbuilding puzzle is finding a beater worth flying rather than building around the pegasus itself.
