Wingmate Roc
Raid asked you to commit to combat before you got paid, and few cards cashed that check as cleanly as this one. The trigger checks whether you attacked this turn, not whether the attack connected or survived, so the puzzle is purely one of sequencing: swing first, then deploy, and five mana buys two flyers plus a board built to grind. Get it backwards (dropping it on a stalled turn, or before you've committed an attacker) and you have a lone 3/4 flier that flatters no one. That conditional doubling is the whole tension, and it rewards a deck already aggressive enough to attack on the turn it wants to develop. The lifegain rider is the underrated half: once both Rocs are airborne, every alpha strike refunds life by the headcount, which turns a tempo play into a body that wins races the beatdown deck usually loses to burn or a bigger board. White midrange has long wanted a single card that stabilizes and closes at once, and a matched pair of evasive bodies paired to an attack-scaling lifegain engine does both from one slot. The catch is that it only delivers when you've already chosen to be the aggressor; it does nothing for the deck sitting back, and that alignment is exactly what the design intends.
