Cut Propulsion

Removal that outsources the damage to the creature you're trying to kill is a neat inversion of how burn usually works: instead of scaling your spell to the threat, you scale the threat against itself. The bigger the attacker, the harder it hits the ground, which flips the usual math where large creatures shrug off cheap red spells. A 6-power beater takes six; a 2-power dork takes two and often survives. That power-based scaling means it whiffs on the small, resilient bodies red normally struggles to answer anyway, and it can't touch anything with zero power, so the design is honest about being a big-creature answer rather than a catch-all. The flying rider is where the intent shows through: doubling the self-inflicted damage against fliers pushes it past the toughness a typical evasive threat carries, so a creature that would otherwise survive its own power gets buried. Red has a long history of caring about power over toughness (fight effects, deals-damage-equal-to-power spells, the whole "your creature versus theirs" lineage), and this sits squarely in that tradition while skipping the part where your own creature has to be involved. It asks the target to do the work, then asks fliers to do twice as much.
