Spider-Man India + Crystalline Crawler + Pearl Medallion + Kor Skyfisher

Spider-Man India

Crystalline Crawler

Pearl Medallion

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 loop transforms a simple self-bouncing creature into an infinite engine by leveraging cost reduction and mana conversion. With Pearl Medallion reducing its cost, Kor Skyfisher can be cast for just {W}, and its mandatory enters-the-battlefield trigger conveniently returns itself straight back to your hand. Meanwhile, Spider-Man India exploits this endless casting loop by triggering its Pavitr's Sevā ability whenever a creature spell is cast, distributing +1/+1 counters onto Crystalline Crawler. Finally, Crystalline Crawler converts those accumulated counters back into the exact white mana needed to recast the Skyfisher, sustaining the cycle indefinitely while generating infinite storm count and trigger effects.
