Spider-Man India + Crystalline Crawler + Kor Skyfisher + The Wind Crystal

Spider-Man India

Crystalline Crawler

Kor Skyfisher

The Wind Crystal

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 relies on Kor Skyfisher repeatedly bouncing itself back to your hand as it enters the battlefield, with its tax conveniently softened by The Wind Crystal lowering white spell costs so it can be recast for just a single white mana. Each time you cast Kor Skyfisher, Spider-Man India triggers to grow your board, dropping a +1/+1 counter straight onto Crystalline Crawler. You can then immediately cash in that very counter using Crystalline Crawler's ability to generate the exact mana needed to recast Kor Skyfisher, keeping the self-sustaining cycle spinning indefinitely.
