Orvar, the All-Form + Clockspinning + Chromatic Orrery + Mirror Box

Orvar, the All-Form

Clockspinning

Chromatic Orrery

Mirror Box

How it works

1. Activate Chromatic Orrery's first ability by tapping it, adding 5.
2. Cast Clockspinning with buyback by paying 4, targeting Chromatic Orrery.
3. Orvar's first ability triggers, creating a token copy of Chromatic Orrery.
4. Resolve Clockspinning, returning it to your hand.
5. Repeat.
6. Once you have infinite mana, you may instead activate the Chromatic Orrery tokens using their second abilities, or target any other permanent.

This clever loop turns a modest targeting spell into an engine for absolute dominance. By casting Clockspinning to manipulate counters on Chromatic Orrery, you trigger Orvar, the All-Form to copy the Orrery over and over again, easily covering the buyback cost thanks to the massive mana production. Meanwhile, Mirror Box quietly ensures your growing army of legendary artifacts doesn't self-destruct to the legend rule, allowing you to flood the board and ultimately tap your endless Orrery copies to draw your entire deck.
