Haywire Mite

Removal that costs nothing to run until the game hands it a target: that is the puzzle this small insect solves. Green's answer to a Stony Silence or a Chalice of the Void used to be something narrow that sat inert until the matchup came around. Here the effect folds onto a 1/1 body worth having anyway. That body counts as an artifact for the decks that tally them, a creature for sacrifice fodder and go-wide plans, and generic chaff otherwise; then, when the game demands it, one green mana converts it into exile-based removal that no regeneration or indestructibility survives. Read the fence in the oracle text: the target must be a noncreature artifact or noncreature enchantment, so a Chalice or an Oblivion Ring is fair game while an artifact creature or enchantment creature is not. That restriction is precisely the price that lets green have this effect on so cheap a package. The death trigger stops it from rotting in hand against opponents who present nothing to exile: it trades in combat, feeds an aristocrats engine, and banks two life whenever it hits the graveyard. Everything hinges on the split cost. One generic to deploy, colorless enough for any shell; one green to activate, gating the payoff behind the color that earned it. That division is what lets decks with no room for dedicated hate maindeck it anyway.
