Spider-Man India + Crystalline Crawler + Centaur Omenreader + Whitemane Lion

Spider-Man India

Crystalline Crawler

Centaur Omenreader

Whitemane Lion

How it works

1. Cast Whitemane Lion by paying .
2. Spider-Man India triggers, putting a +1/+1 counter on Crystalline Crawler.
3. When Whitemane Lion enters, it triggers, returning itself from the battlefield to your hand.
4. Activate Crystalline Crawler by removing a +1/+1 counter from it, adding .
5. Repeat.

This clever loop turns the self-bouncing nature of Whitemane Lion into a perpetual motion machine, fueled entirely by the color-fixing mana of Crystalline Crawler. Whenever Whitemane Lion enters the battlefield, its triggered ability immediately returns it to your hand, setting up the next iteration while also triggering Spider-Man India to hand out a +1/+1 counter. That counter is then spent to activate Crystalline Crawler, generating the exact white mana needed to recast the Lion, all while Centaur Omenreader sits tapped on the board to make that creature spell completely free.
