Decommission

Naturalize, Disenchant, and the long line of white-and-green answers to artifacts and enchantments have always priced themselves at two mana for a reason: the effect is reactive, situational, and dead in too many matchups to ask more. Push the floor to three mana and the design owes something back, so revolt hands you a three-life rebate: a condition checked as the spell resolves, not a separate trigger, which simply asks whether a permanent already left your battlefield under your control earlier in the turn. The wrinkle is the sequencing it rewards. A cracked fetch, a sacrificed token, an attacker traded in combat, a creature dying before you cast this: any of them flips the payoff on, and the ordering is entirely on you, because revolt reads the board state at resolution and takes it or leaves it. Fail to satisfy the clause and you have simply paid one extra mana for the same disenchant effect the color pie has carried since its earliest sets. Satisfy it and the life is a consolation prize riding on the answer you actually needed. Strip the rider and nothing distinguishes this from a dozen functional siblings; the rider does just enough to justify the third mana without ever pretending to be the reason you run the card. It is a removal spell that quietly rewards thinking about the order you spend your turn, no more and no less.
