This clever loop relies on Stonecloaker's flash and its self-bouncing entry trigger to continuously re-enter the battlefield for just a single white mana. Cemetery Prowler quietly reduces that casting cost to make the loop self-sustaining, while Spider-Man India capitalizes on each cast by growing your board and granting flying. Finally, Crystalline Crawler acts as the mana engine, trading the +1/+1 counters generated by Spider-Man India back into the white mana needed to recast Stonecloaker and keep the chain going indefinitely.
