Persist gave green-white a body that fights twice, and this is the keyword in its plainest housing: a 2/2 whose entire reason for existing is that it comes back the first time it dies. Everything turns on how the -1/-1 counter prices that second life. It returns a 1/1, smaller and now disqualified from persisting again, so the encore is strictly worse and strictly final. That single counter is the line between a sticky blocker and an infinite loop, and it is also the exact lever value decks learned to pull. Pair persist with a way to erase the counter (laying a +1/+1 counter on top to cancel it out, or stripping counters wholesale) and the creature resets to a fresh persister, ready to die and return again. Add a no-cost way to sacrifice it alongside a payoff that fires on death or entry, and the two-drop stops being the value play and becomes the engine. On its own it is honest enough: a hatebear-sized creature that demands two removal spells or one piece of exile to answer for good. The interest lives entirely in how readily that counter can be removed, which is why this kind of design surfaces wherever a format has the tools to manipulate counters and reasons to want creatures dying on a loop.
