Ghalta, Stampede Tyrant + Cloudstone Curio + Spark Double

Ghalta, Stampede Tyrant

Cloudstone Curio

Spark Double

How it works

1. Cast Ghalta by paying 5.
2. When Ghalta enters the battlefield, it and Cloudstone Curio trigger.
3. Resolve the Cloudstone Curio trigger, returning Spark Double to your hand if its on the battlefield, or returning nothing to your hand otherwise.
4. Resolve the Ghalta trigger, putting Spark Double onto the battlefield as a copy of Ghalta from your hand.
5. When Spark Double enters the battlefield, it and Cloudstone Curio trigger.
6. Resolve the Cloudstone Curio trigger, returning Ghalta to your hand from the battlefield.
7. Resolve the Spark Double trigger, putting Ghalta onto the battlefield from your hand.
8. Repeat from step 2.

This clever loop hinges on the interplay between Ghalta, Stampede Tyrant and Cloudstone Curio, where Ghalta's massive entry trigger dumps your hand and sets off the Curio's bounce ability. By dropping Spark Double as a nonlegendary copy of Ghalta, you create a seamless swapping mechanism that bypasses the legend rule entirely. Every iteration lets Spark Double and Ghalta, Stampede Tyrant endlessly ping Cloudstone Curio to pick each other back up, generating infinite creature enters-and-leaves-the-battlefield triggers.
