Deadshot Minotaur

The narrow answer with a refund built in. Conditional removal has always carried the same liability: a creature whose enters-the-battlefield trigger only fires against flyers is dead weight in any matchup with nothing in the air. The fix is cycling, and specifically a hybrid cost payable with either color in its identity, so the card collapses back into a fresh draw the moment there is nothing aloft to shoot. That gives it two distinct modes from one slot: an answer to evasive threats when you need it, a cantrip when you do not. The 3/4 body is what earns its keep when the trigger does land, large enough to trade up in combat and outlive most of what it just shot down rather than evaporating after its one job. The trigger's reach is deliberately capped: it requires a creature with flying as the target, so it cannot be pointed at a planeswalker, a player, or a grounded threat, the restriction that keeps a five-mana three-damage burst from creeping into generic removal territory. What it represents is a clean resolution to the perennial problem of the situational maindeck card: rather than asking you to draw the right tool against the right deck and stranding you when you guess wrong, it hands you the tool and a refund if the matchup never arrives.
