Mordant Dragon

The firebreathing Dragon archetype usually stops at "swings hard, threatens reach": pump the power, point it at the face, hope it sticks. This one adds a second barrel to the combat math by mirroring its damage onto a creature the defending player controls. Because the trigger keys off how much combat damage it deals to a player, the firebreathing activation does double duty: every you sink into power before damage doesn't just hit harder, it widens the secondary blast that wipes a blocker-in-waiting or a key utility creature off the table. That coupling is the whole design idea. It takes a 5/5 flier whose pump line was already a serviceable clock and turns it into an attacker that taxes the opponent's board for the privilege of taking the hit: the defender either trades a creature into the air or watches one die the moment the player takes damage. The routing is what keeps it from being oppressive. The mirrored damage only lands when combat damage reaches a player, so a chump block or a single sturdy flier shuts the rider off entirely, and the secondary hit can only point at a creature that same player controls. It rewards the firebreathing color's instinct to flood mana into a single threat, then converts that excess into removal-on-a-swing, all bolted to a body that closes from the air on its own.
