Keen Glidemaster

A repeatable evasion engine wrapped in a body that also wants to swing: the 2/1 stats invite early attacks, while the three-mana activation to grant flying keeps working long after the ground stalls out, pushing a creature through turn after turn or lifting a wide team into the air once the mana comes online. The ability targets any creature, not just this one and not just your own board, so it doubles as a combat trick without a card: fly to slip past blockers, fly to reach an attacker in the air on defense. That flexibility is the whole appeal, but the arithmetic sets a ceiling. Three mana per grant is a heavy tax to pay again and again, which means the effect rewards a board that already has the initiative rather than one trying to claw back from behind; you spend the activation to close a game you are winning, not to survive one you are losing. This is the evasion-granting utility creature in its familiar form, a lineage of role-players built to give a deck with plenty of bodies one more angle of attack. It fills the gap where the board is full but nothing gets through, and it asks for mana rather than a card to do it.
