God-Eternal Kefnet's triggered ability lets the pilot copy Capture of Jingzhou for 1UU whenever it's drawn off the top; Isochron Scepter imprinting Brainstorm puts it back there every end step before the turn begins. The Scepter's activation at 2 mana and Kefnet's copy cost of 1UU mean the minimum viable mana base is 3UU per full loop — not free, but mono-blue ramp handles it cleanly.

How it works
01
Prerequisites
—
02
Steps
- During the end step before your turn, activate Isochron Scepter by paying
and tapping it, casting a copy of Brainstorm without paying its mana cost. - Resolve Brainstorm, causing you to draw three cards and put Capture of Jingzhou and another card on top of your library, ensuring Capture of Jingzhou is the topmost card.
- Move to your turn, drawing and revealing Capture of Jingzhou during your draw step.
- God-Eternal Kefnet's first ability triggers, causing you to pay
to cast a copy of Capture of Jingzhou. - Resolve the copy of Capture of Jingzhou, causing you to take an extra turn after this one.
- Activate Isochron Scepter by paying and tapping it, casting a copy of Brainstorm without paying its mana cost.
- Repeat from step 2.

Result
Infinite turns; Lock
Variations
Cheaper, tighter, alternate lines
Temporal Manipulation and Time Warp replace Capture of Jingzhou at the same 1UU copy cost and are identical in function; Expropriate does not — Kefnet can copy it but the opponent vote ruins the lock. If Brainstorm is unavailable, Ponder or Preordain on the Scepter can set up the topdeck but require more manipulation steps, making Brainstorm the only reliable imprint target here.
