Obstinate Gargoyle

The flying clause and Persist are built to feed each other, and that dovetailing is the whole point. Persist wants to bring the body back cheaply, and each return arrives with a -1/-1 counter, which counts as a modification, which is exactly what switches the flying on. So the recursion that usually reads as a downside (a shrinking body) doubles as the evasion trigger: the reanimated 1/1 comes back airborne. Any Equipment, Aura, or +1/+1 counter does the same job without spending the persist trigger, letting it play nicely with the tools a +1/+1 shell already runs. The counter interaction cuts both ways, though. A +1/+1 counter annihilates the -1/-1 counter Persist leaves behind, which both refills the toughness and resets the persist eligibility, so the same shell that turns on flight can also reload the loop for another death. Left alone, it is a two-life engine: die, come back diminished but flying, die again and stay dead. Layer in counter manipulation and it becomes something you can keep spinning. Attaching a modifier to the fresh body and feeding it to a sacrifice outlet is the natural line, since the ground 2/2 becomes a flying threat on the way out, returns as a flying 1/1, and stays in the air as long as it stays modified. The counter mechanic pulls double duty as both the evasion switch and the dial that decides how long the recursion runs.
