Spider-Man India + Crystalline Crawler + Semblance Anvil + Kor Skyfisher

Spider-Man India

Crystalline Crawler

Semblance Anvil

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 elegant loop turns the humble Kor Skyfisher into a self-sustaining engine by exploiting its own entry trigger to bounce itself right back to your hand for just a single white mana. To make this cost-effective, Semblance Anvil reduces the Skyfisher's cost down to nothing, while Spider-Man India swoops in whenever you cast a creature spell to distribute +1/+1 counters and flying. These very counters are then harvested by Crystalline Crawler, which converts them back into the exact white mana needed to recast the Skyfisher over and over again.
