Mirrorwing Dragon

The trick that turns single-target spells into multi-target ones, built backward from the way most players think about pump spells and protection. Point a Giant Growth at the dragon and it forks for every other creature you control; the copies are generated for whoever cast the original, so the relay always works in their favor. The clause is narrow on purpose: the spell must target only this creature, so anything with a second target slot or a sweep already baked in slips past the trigger entirely. That same narrowness sets a quiet trap for opponents. A piece of targeted burn or a single-target removal spell aimed at the dragon copies itself across the caster's own board, handing them a one-sided wipe of their team (edicts and other player-targeting effects are safe, since they never point at the creature in the first place). It rewires combat math by making one body into a distribution hub for any instant or sorcery cheap enough to want to chain. The 4/5 flier matters as much as the ability: hard enough to kill cleanly that opponents are often forced to interact in ways that feed the engine, and large enough to threaten on its own while you assemble the spells that justify it. Among red Dragons that ask you to play differently rather than just bigger, its central question is not "how do I cast it" but "how do I aim everything at it."
