Ashaya, Soul of the Wild + Cloudstone Curio + Crookshank Kobolds + Maja, Bretagard Protector

Ashaya, Soul of the Wild

Cloudstone Curio

Crookshank Kobolds

Maja, Bretagard Protector

How it works

1. Cast Crookshank Kobolds by paying 0.
2. When Crookshank Kobolds enters the battlefield as a Forest land due to Ashaya, it and Maja trigger.
3. Resolve the Cloudstone Curio trigger, choosing to return nothing to your hand.
4. Resolve the Maja trigger, creating a 1/1 Human Warrior creature token.
5. When the Human Warrior enters the battlefield, Cloudstone Curio triggers, returning Crookshank Kobolds to your hand from the battlefield.
6. Repeat.

This loop relies on Ashaya, Soul of the Wild to transform your creatures into lands, allowing free drops like Crookshank Kobolds to trigger both land-based abilities and permanent-bouncing engines. As the Kobolds enter, they simultaneously trigger Cloudstone Curio and Maja, Bretagard Protector, the latter of which responds to the new "land" by spawning a 1/1 Human Warrior token. That token's subsequent entrance triggers Cloudstone Curio anew, bouncing the original Kobolds back to your hand so you can recast them indefinitely while growing an overwhelming army fueled by Maja's landfall production.
