Anticausal Vestige + Cloudstone Curio + Gigantoplasm

Anticausal Vestige

Cloudstone Curio

Gigantoplasm

How it works

1. Cast Gigantoplasm by paying its mana cost. Choose to have it enter as a copy of Anticausal Vestige.
2. When Gigantoplasm 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 Gigantoplasm from the battlefield to your hand.
5. When Gigantoplasm leaves the battlefield, it triggers, causing you to draw a card and put Gigantoplasm from your hand onto the battlefield as a copy of Anticausal Vestige.
6. Repeat from step 2.

This mesmerizing loop hinges on the clever interplay between Cloudstone Curio and a pair of interchangeable clones. By casting Gigantoplasm as a copy of Anticausal Vestige, you set up a perpetual game of tag: whenever one enters the battlefield, Cloudstone Curio triggers to bounce the other back to your hand. Because each creature constantly leaves the battlefield in the process, Anticausal Vestige's leave-the-battlefield trigger fires repeatedly, drawing you an endless stream of cards while smoothly cycling your creatures right back onto the board.
