Shriekgeist

Stapling mill to a combat-damage trigger instead of an activation reframes the whole proposition: this is an evasive flyer whose damage trigger feeds a graveyard rather than ticks down a clock. Two cards a swing is slow, grinding deck-depletion that only pays off in a build committed to the long game, and that commitment is the real cost. Nobody empties a library two cards at a time without either accepting a multi-turn race or treating the mill as fuel for a graveyard payoff rather than as the win condition itself. The flying body is the part doing the honest work: it pressures life totals on its own, slips past ground blockers, and keeps the card relevant even when the mill is not. In Spirit shells the evasive 1/1 with a useful creature type tends to earn its slot more reliably than the milling does. The trigger is the seasoning, not the meal: a reminder that combat damage can be made to do something other than reduce a life total, and an early instance of mill attached to a creature whose attack pattern, not a sacrifice or a tap ability, governs the rate.
