Stormwing Dragon

The design lives entirely in the flip. Deployed for its full cost, it is a fair-but-forgettable 3/3 flier with first strike, a body no one builds around. The line that earns the card asks you to conceal it as a nondescript 2/2 for three, bank the seven-mana megamorph, and pick the turn when the reveal becomes a board-wide anthem: a counter on the Dragon itself and a counter on each other Dragon you already control. That payoff scales with how much of the tribe you have committed, which makes the card a build-around folded inside a build-around. The reward loads toward the late game and toward a board stocked with Dragons, so it is weakest exactly where a flier is most tempting (early, and alone) and strongest once the wings are already down. The seven-mana flip is the restraint that keeps the trigger honest: it is never the cheap pump you want on curve, only the one you have sequenced your way into. That is the deliberate trade the design makes. The face-up rate is kept plain so the reveal can carry the weight: a generically costed Dragon that pays off only as a finisher in a deck built to give the flip enough targets, and one that leaves you a small hidden creature to bluff behind while the board fills in around it.
