Extravagant Replication + Capture of Jingzhou + Timeless Witness

Extravagant Replication

Capture of Jingzhou

Timeless Witness

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

This infinite turn loop is orchestrated by letting Extravagant Replication steadily clone Timeless Witness at the dawn of every upkeep. Each time the Timeless Witness token materializes, its triggered ability reaches into your graveyard to pluck back Capture of Jingzhou, granting you another continuous sequence of extra turns to cast it all over again.
