Anticausal Vestige + Cloudstone Curio + Chameleon, Master of Disguise

Anticausal Vestige

Cloudstone Curio

Chameleon, Master of Disguise

How it works

1. Cast Chameleon either from your hand or from the command zone by paying 3 plus commander tax if applicable. Choose to have it enter as a copy of Anticausal Vestige.
2. When Chameleon enters, Cloudstone Curio triggers, returning Anticausal Vestige from the battlefield to your hand.
3. When Anticausal Vestige leaves the battlefield, it triggers, causing you to draw a card and and put Anticausal Vestige from your hand onto the battlefield.
4. When Anticausal Vestige enters, Cloudstone Curio triggers, returning Chameleon from the battlefield to your hand.
5. When Chameleon leaves the battlefield, it triggers, causing you to draw a card and put Chameleon from your hand onto the battlefield as a copy of Anticausal Vestige.
6. Repeat from step 2.

This cunning loop relies on a clever partnership between Anticausal Vestige and Chameleon, Master of Disguise to continuously bounce one another. With Cloudstone Curio sitting on the battlefield, the entry of one permanent prompts the return of the other to your hand, allowing you to replay them repeatedly. Because Anticausal Vestige and the copy of it created by Chameleon both trigger their leave-the-battlefield abilities when bounced, this perpetual motion machine rewards you with infinite card draw and near-infinite creature triggers.
