This elegant loop relies on the constant recycling of Kitchen Finks, which uses its persist ability to return to the battlefield whenever it dies, provided it has no -1/-1 counters. Carrion Feeder acts as the engine, providing a free and instant outlet to sacrifice Kitchen Finks over and over again. Every time Kitchen Finks re-enters, it triggers a 2-life gain, which in turn causes Spider-Man, Peter Parker to trigger and place a +1/+1 counter on a creature. Because +1/+1 and -1/-1 counters cancel each other out as a state-based action, Kitchen Finks is cleared of its negative counter, resetting its persist ability so the entire sequence can repeat indefinitely for boundless sacrifices, lifegain, and counters.
