Spider-Man India + Crystalline Crawler + Animar, Soul of Elements + Whitemane Lion

Spider-Man India

Crystalline Crawler

Animar, Soul of Elements

Whitemane Lion

How it works

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

This intricate loop hinges on Animar, Soul of Elements steadily reducing the cost of creature spells as it accumulates +1/+1 counters, eventually making Whitemane Lion free to cast for just {W}. Each time you cast the Lion, Spider-Man India triggers to buff Crystalline Crawler with a fresh +1/+1 counter, which you can immediately harvest for mana using the Crawler's ability. Finally, Whitemane Lion's own entry trigger forces it right back to your hand, allowing you to feed the loop indefinitely while spinning up endless triggers for your creature enters-and-leaves-the-battlefield effects.
