This clever loop relies on Stonecloaker's flash and its own self-bouncing entry trigger to continuously re-enter the battlefield for just a single white mana. As Stonecloaker keeps arriving, Spider-Man India triggers to feed a +1/+1 counter onto Crystalline Crawler, which you can immediately remove for mana to pay for the next cast. Meanwhile, Centaur Omenreader quietly discounts those creature spells by making sure you aren't paying extra mana while it's tapped.
