Orvar, the All-Form + Whim of Volrath + Chromatic Orrery + Mirror Box

Orvar, the All-Form

Whim of Volrath

Chromatic Orrery

Mirror Box

How it works

1. Activate Chromatic Orrery's first ability by tapping it, adding 5.
2. Cast Whim of Volrath with buyback by paying 3, targeting Chromatic Orrery.
3. Orvar's first ability triggers, creating a token copy of Chromatic Orrery.
4. Resolve Whim of Volrath, 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 marvelous transmutation relies on Orvar, the All-Form to multiply your resources whenever you target your own permanents with an instant or sorcery. By casting Whim of Volrath with its buyback cost, you trigger Orvar to create a token copy of Chromatic Orrery while returning the spell right back to your hand to cast again. Chromatic Orrery’s ability to produce five colorless mana easily pays for this loop, generating a net surplus of mana each iteration to fund both the buyback and the Orrery's own color-filtering text. Meanwhile, Mirror Box safely nullifies the legendary rule, allowing you to flood the battlefield with an infinite army of Chromatic Orrery tokens and draw your entire deck.
