Tah-Crop Elite

Exert asks a single question at the attack step: is this swing worth losing the creature for a turn? This Bird Warrior puts a team-wide anthem behind that question. The +1/+1 fires only when it swings, only on the turn you commit it, and only if you accept that it stays down through your following turn rather than untapping to block. That constraint turns a would-be static lord into a timing decision. A board-wide buff is worth the most when you have a wide, decisive attack, which is precisely the situation where you also most want the creature standing on defense afterward; exert forces you to choose whether this swing closes the game or whether you need the body back to hold the ground. The flying keeps it useful on the turns you leave it home, so holding it back never leaves you with a dead card. Set against the older anthem-on-a-stick designs that simply hand you a passive buff for the cost of wearing a target, this ration the bonus instead: real, but paid out one attack at a time, with the whole design living in the choice of when to spend it.
