Extravagant Replication + Capture of Jingzhou + Damage Control Crew

Extravagant Replication

Capture of Jingzhou

Damage Control Crew

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

This clever loop locks down endless turns by weaponizing the upkeep trigger of Extravagant Replication to constantly clone Damage Control Crew. As each new copy enters the battlefield, its Repair ability triggers to fish Capture of Jingzhou right back out of your graveyard and into your hand, letting you cast it again to secure another extra turn. Because Extravagant Replication generates a fresh token at the start of every single turn, you can repeat this cycle indefinitely without ever running out of fuel.
