Mutinous Massacre

The parity clause is the whole trick, and it is a nastier lever than the one-sided sweepers it descends from. Splitting the board by odd or even mana value means the destruction and the theft key off the same quality: whatever you wipe, everything that survives falls under your control, then swings for you. A caster whose curve clusters on even values (or odd) can arrange a board where the sorcery reads as a lopsided Insurrection stapled to a Damnation, one that takes exactly what it does not first destroy. The seven-mana price and the double-color commitment on both ends are what pay for that: this is not a reactive answer but a turn you build toward, a single detonation timed for the moment your own board sits safely inside one parity. Untap, haste, and end-of-turn control on the survivors fold a defensive sweep and an alpha strike into the same cast, which is the tension the parity requirement resolves: a card that both clears the way and hands you the army has to make you choose what it cannot do, and here the choice is a number's parity. The "zero is even" line is the fine print that decides where tokens land: call even and your zero-cost tokens die with everything else even, while calling odd destroys the odd creatures and leaves those tokens standing, ready to come under your control alongside the rest of the survivors.
