This clever loop revolves around casting and bouncing Kor Skyfisher over and over, turning its self-returning entry trigger into an engine when paired with Spider-Man India. As Spider-Man India tracks your creature spells, every iteration grows Crystalline Crawler with +1/+1 counters—which Crystalline Crawler can immediately convert back into the white mana required to recast Kor Skyfisher. Meanwhile, Temur Battlecrier stands ready to help grease the wheels of your mana economy by discounting your spells based on your pumped-up creatures' power.
