Extravagant Replication + Capture of Jingzhou + Zealous Lorecaster

Extravagant Replication

Capture of Jingzhou

Zealous Lorecaster

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

This elegant loop lets you chain infinite turns by weaponizing your upkeep step, relying on Extravagant Replication to constantly clone your board state. Every time a fresh token copy of Zealous Lorecaster enters the battlefield, its triggered ability salvages Capture of Jingzhou right back out of your graveyard and into your hand, ready to be cast anew. Because Capture of Jingzhou grants you a subsequent turn to untap and fuel this engine again, Extravagant Replication will trigger like clockwork at the dawn of each new upkeep to repeat the cycle indefinitely.
