Derevi, Empyrial Tactician + Cloudstone Curio + Chromatic Orrery

Derevi, Empyrial Tactician

Cloudstone Curio

Chromatic Orrery

How it works

1. Activate Chromatic Orrery's first ability by tapping it, adding 5.
2. Cast a nonartifact creature card from your hand by paying at most 2.
3. When the creature enters the battlefield, Cloudstone Curio triggers, returning Derevi from the battlefield to your hand.
4. Cast Derevi by paying 3.
5. When Derevi enters the battlefield, it and Cloudstone Curio trigger.
6. Resolve the Cloudstone Curio trigger, returning the creature cast in step 2 from the battlefield to your hand.
7. Resolve the Derevi trigger, untapping Cloudstone Curio.
8. Repeat.

This fascinating loop turns a simple dance of creature entries into an endless engine of resources, fueled entirely by the mana-producing potential of Chromatic Orrery. By casting a cheap nonartifact creature, you trigger Cloudstone Curio to bounce Derevi, Empyrial Tactician back to your hand, setting up a continuous cycle of repeatable casting. When Derevi enters the battlefield, its triggered ability untaps Chromatic Orrery—which conveniently fixes your mana needs so you can easily pay for Derevi's commander tax or alternative costs—while Cloudstone Curio bounces your initial creature right back to your hand to start the process over again.
