Stonebinder's Familiar

Exile-matters had long been a graveyard-hate mechanic in search of a reason to run it, and this one-drop supplies the reason by turning the act of exiling into growth. The trigger keys off the exiling itself, not the source: your own graveyard hate, flicker effects, foretell, adventure casts, impulse-draw, processing an opponent's yard, any of it feeds the counter. The tension lives in the once-per-turn clamp. Without it, a white body that grew every time a card left for exile would be trivially exploitable in a shell built to churn exile triggers; the limiter turns a potential runaway into a steady, one-counter-a-turn accrual that rewards a whole board committed to a mechanic rather than a single busted loop. What makes it strange is that the ability doesn't care whose cards get exiled or why, only that it happens during your turn, so the same 1/1 slots into a flicker deck, a foretell shell, and a dedicated graveyard-hate build with equal comfort. It's a rare instance of a "your turn" restriction doing double duty: it fences off cheesy instant-speed exile at the opponent's leisure while quietly nudging you toward proactive plans. A body that converts incidental exile into a clock, priced so the payoff has to earn its keep across a whole game rather than spiking in one.
