Spider-Man India + Crystalline Crawler + Stonecloaker + Planar Gate

Spider-Man India

Crystalline Crawler

Stonecloaker

Planar Gate

How it works

1. Cast Stonecloaker by paying .
2. Spider-Man India triggers, putting a +1/+1 counter on Crystalline Crawler.
3. When Stonecloaker 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 Planar Gate to slash Stonecloaker's casting cost down to a single white mana, allowing you to repeatedly deploy it with flash. Each time Stonecloaker enters the battlefield, its own trigger forces it right back to your hand, while simultaneously triggering Spider-Man India to distribute a +1/+1 counter. That counter lands squarely on Crystalline Crawler, which can then be immediately tapped or stripped of a counter to generate the exact white mana needed to start the cycle over again.
