Self-Destruct

A creature's own power turned into a two-way blast, dealt back onto the creature itself. The math is symmetrical and unforgiving: whatever damage this deals outward, it deals right back to the creature pointing the gun, so the effect scales directly with the body you are willing to spend. It reads as a straight trade until the second target clause registers: the outgoing damage can hit any other target, so a large attacker you were about to lose in combat, or a creature already marked for death, can cash itself in for reach to the face or a two-for-one on the board. The design leans into the aristocrats logic of a creature being worth more dead than alive, but delivers it as an instant rather than a sacrifice outlet, so the whole exchange resolves at the speed of a combat trick or an end-step ambush. The catch is that you need a genuinely large body for the payoff to justify the self-damage, and X being locked to power means a pumped attacker or an inflated token is where the numbers get interesting. Think of it as burn that draws its damage from a creature you already control: a narrower, more deliberate tool than a generic bolt, and one that turns a dying threat into its own last word.
