Ghalta, Stampede Tyrant + Cloudstone Curio + Mirror Box + Clone

Ghalta, Stampede Tyrant

Cloudstone Curio

Mirror Box

Clone

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 Clone to your hand if its on the battlefield, or returning nothing to your hand otherwise.
4. Resolve the Ghalta trigger, putting Clone onto the battlefield as a copy of Ghalta from your hand.
5. When Clone 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 Clone trigger, putting Ghalta onto the battlefield from your hand.
8. Repeat from step 2.

This clever loop relies on Ghalta, Stampede Tyrant and a Clone entering the battlefield as a copy of it, creating an endless cycle of mutual rescue through Cloudstone Curio. Whenever Ghalta hits the board, its ability drops the Clone from your hand, while the Curio triggers to bounce the original Ghalta back home; then, when the Clone enters as another copy of Ghalta, its own entry triggers the Curio to bounce the first, allowing you to alternate casting them back and forth. Meanwhile, Mirror Box does the heavy lifting of bypassing the legend rule entirely, letting these legendary titans swap places without any of them hitting the graveyard.
