Spider-Man India + Crystalline Crawler + Urza's Incubator + Kor Skyfisher

Spider-Man India

Crystalline Crawler

Urza's Incubator

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 relies on Kor Skyfisher entering the battlefield for a single white mana, which is made possible by reducing its cost with Urza's Incubator naming Artificer, Kor, or Soldier. Each time Kor Skyfisher hits the board, its own trigger forces it right back to your hand while Spider-Man India triggers to grow your board and grant flying. Meanwhile, Crystalline Crawler acts as our colorful battery, feeding on the counters placed by Spider-Man India so we can strip them away for the exact white mana needed to recast Kor Skyfisher over and over again.
