Spider-Man India + Crystalline Crawler + The Immortal Sun + Kor Skyfisher

Spider-Man India

Crystalline Crawler

The Immortal Sun

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 ingenious loop relies on a cost-reducing engine combined with self-bouncing permanents to generate an endless cycle of creature entries and leaves. With The Immortal Sun lowering costs so that Kor Skyfisher can be cast for just a single white mana, casting it triggers Spider-Man India to steadily empower your board while feeding counters into Crystalline Crawler. Whenever Kor Skyfisher enters the battlefield, its own mandatory return trigger bounces it right back to your hand, fueling the next iteration while Crystalline Crawler converts its accumulated +1/+1 counters back into the exact white mana needed to pay for the spell all over again.
