Extravagant Replication + Eternal Witness + Capture of Jingzhou

Extravagant Replication

Eternal Witness

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou by paying its mana cost, causing you to take an extra turn after this one.
2. Move to your next turn.
3. At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Eternal Witness.
4. When the Eternal Witness token enters the battlefield, it triggers, returning Capture of Jingzhou from your graveyard to your hand.
5. Repeat.

This brilliant temporal loop harnesses the steady compounding growth of Extravagant Replication to achieve infinite turns. By casting Capture of Jingzhou, you pay the path for your extra turns, which then feed back into themselves with the help of a resilient graveyard strategy. At the start of each new upkeep, Extravagant Replication churns out a fresh copy of Eternal Witness. As that token enters the battlefield, its triggered ability plucks Capture of Jingzhou right back out of your graveyard and into your hand, ready to be cast again and keep the cycle spinning endlessly.
