Extravagant Replication + Warden of the Eye + Capture of Jingzhou

Extravagant Replication

Warden of the Eye

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 Warden of the Eye.
4. When the Warden of the Eye token enters the battlefield, it triggers, returning Capture of Jingzhou from your graveyard to your hand.
5. Repeat.

This cunning combination achieves infinite turns by looping a powerful sorcery with a recurring creature trigger. You start by casting Capture of Jingzhou to earn an extra turn, letting it drop safely into your graveyard upon resolution. From there, Extravagant Replication handles the heavy lifting each upkeep by conjuring a fresh token copy of Warden of the Eye. The Warden of the Eye token's enters-the-battlefield ability then does the crucial recursion work, plucking Capture of Jingzhou right back out of your graveyard and back into your hand, ready to be cast all over again.
