Spider-Man India + Crystalline Crawler + Cloud Key + Kor Skyfisher

Spider-Man India

Crystalline Crawler

Cloud Key

Kor Skyfisher

How it works

1. Cast Kor Skyfisher by paying .
2. Spider-Man India triggers, putting a +1/+1 counter on Crystalline Crawler.
3. When Kor Skyfisher 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 Kor Skyfisher into an infinite engine by leveraging a few key cost reducers and mana sources. With Cloud Key naming creatures, Kor Skyfisher's cost is reduced to just a single white mana, allowing you to recast it repeatedly. Each time you cast the Skyfisher, Spider-Man India triggers to bolster Crystalline Crawler with a fresh +1/+1 counter. That counter can immediately be cashed in using Crystalline Crawler's ability to generate the white mana needed to start the cycle all over again, while Kor Skyfisher's own entry trigger keeps bouncing itself right back to your hand.
