Stonerise Spirit

The 1/2 flier is throwaway; the reason to run this is the repeatable evasion grant stapled to it. For four mana and one card exiled from your graveyard, any creature gains flying until end of turn, which is exactly enough to push a grounded fatty over the last blocker on a stalled board. That is the entire pitch. What keeps it from being a free reach-machine is the graveyard exile: in any deck that wants its bin for something (delve, flashback, escape, and every other recursion payoff draw from the same well), each activation is a card spent here instead of there. Lean on the valve and you drain the resource that fuels your other plans; the engine eats its own tail. It belongs to a long tradition of white commons that pair a cheap evader with a repeatable way to grant flight, built to give a slow, grindy deck a route through the air once it has finally taken control of the ground. The body is not the point. The ability is a self-limiting spigot for turning a ground stall into a finish, priced steep enough (four mana plus a card, every time) that it never becomes the plan on its own.
