Wildfire Cerberus

Monstrosity always carried a question: what do you actually get when you finally pay the back-end cost? Most of the cycle answered with a stat bump and a small rider; this one answers with a sweep aimed at one side of the table. The seven-mana activation is steep, and a 4/3 body asks to be killed long before you assemble it, so the payoff has to earn all that patience. When it goes monstrous, two damage hits each opponent and every creature they control while leaving your own board untouched: a one-sided board wipe stapled to a creature, with the upside of chipping the player's life total on top. That asymmetry is what makes the wait worth it. The trigger fires on becoming monstrous rather than on the activation itself, so it resolves cleanly as a single state change, not a stack of pings you have to babysit. Against a wide, low-toughness board it reads as a delayed, repeatable-once Pyroclasm that doesn't cost you the dork or weenie you just deployed, plus a 5/4 left over to attack with. The catch is one monstrosity always imposes: spend that much mana on a defensive sweep and you've skipped a turn of doing anything else. Built to reward a deck that can stall to the late game and then turn one card into both removal and reach.
