Battlewing Mystic

The kicker cost is where this bird earns its keep. Unkicked, it's a plain 2/1 flier, the kind of two-drop that trades in the air and gets forgotten. Pay the extra red and it becomes something stranger: a creature that folds a full-hand refill onto an evasive threat, but only by throwing away everything you're holding first. The discard-then-draw clause is a wheel effect miniaturized and stapled to a permanent, which means the card punishes you for hoarding value and rewards you for having already spent it. Play it with an empty grip and it's a clean two-card draw; play it holding business and you're incinerating cards you presumably wanted. The kicker isn't a straightforward upgrade, then, so much as a wager on when your hand has become dead weight worth burning down. It also quietly asks for a red splash, since the flier itself is monoblue but the payoff lives off-color, a small deckbuilding cost that stops the effect from coming for nothing. This is the loot-and-refill lineage compressed onto a body, kin to the wheel family rather than any grind-out card-advantage engine, with the aggressive twist that you'd rather cast it late, tapped out, running on fumes, than early with a full hand you'd hate to lose.
