Scourge of Kher Ridges

Most board-clearing dragons sweep one way; this one carries two switchboards on the same body. The cheaper activation scrapes the ground for two mana, dealing two damage to every nonflyer while leaving its own 6/6 frame and any allied flyers untouched, so it polices a board of small creatures one sweep at a time without ever risking itself. The expensive activation flips the axis entirely: six damage to every other flyer, a number tuned to kill almost any other dragon, angel, or sphinx in the air while this one shrugs the whole burst off. That asymmetry is the design idea. Both abilities are repeatable damage the creature is constitutionally immune to, so a long game becomes a question of how much red mana you can pour into clearing whichever half of the battlefield matters. The eight-mana cost and the per-use price are what keep it from being oppressive: neither sweep requires tapping it, so a player with enough open mana can land it and immediately scour the ground, but each activation is real red spent rather than a free trigger, and the body holds the sky the moment it arrives. Where the expensive red dragons that double as removal engines tend to answer one threat per turn, this one answers a category at a time, choosing its plane and grinding it flat.
