This clever loop is orchestrated by Spider-Man India, whose alternative cost allows you to effortlessly bounce a tapped creature to cast your spells on the cheap. That cost reduction is further supercharged by Temur Battlecrier, whose passive discount ensures your creatures slide out for minimal investment. As Stonecloaker enters the fray repeatedly to bounce itself back to your hand, it triggers Spider-Man India to continually buff Crystalline Crawler with fresh +1/+1 counters. Crystalline Crawler then cashes in those very counters to generate the exact white mana needed to recast Stonecloaker, fueling an endless cycle that endlessly triggers enters-the-battlefield and leaves-the-battlefield effects.
