Kilnmouth Dragon

Amplify made the count of Dragons in your hand a resource, and Kilnmouth Dragon is where that count becomes a damage faucet. Each Dragon you reveal as it enters adds three counters, so a full reveal of three brings the printed 5/5 onto the battlefield as a 14/14 flier; the tap ability then fires that whole counter total at any target, recurring every turn so long as the body survives. That second clause is what separates it from the rest of the Amplify cycle: the others bank their counters into combat math, while this one converts them into a repeatable burn engine that ignores blockers entirely. The structural tension is the hand cost. Amplify rewards you for hoarding Dragons, but every Dragon you reveal is one you have not cast, so the card pulls you toward a top-heavy hand right when you most want to be deploying threats. Reveal nothing and you have paid seven mana for a 5/5 flier whose tap ability does literally nothing (zero counters, zero damage), a removal-attracting beater with a dead button; reveal a fistful and you have a one-card win condition that pressures both the opponent's life total and their board from a single tapped permanent. It is the rare creature whose ceiling and floor are both decided before it ever attacks, set entirely by what you were willing to keep in hand.
