Phantom Steed creates a token copy of Eternal Witness whenever it deals combat damage to a player; that token's enter-the-battlefield trigger returns Capture of Jingzhou from the graveyard to hand, ready to cast on the extra turn. The lock is airtight once assembled — each cycle reloads the Time Walk effect without spending additional resources beyond the attack step.

Recipe

How it works

Prerequisites

An opponent can not block Phantom Steed.

Steps

Cast Capture of Jingzhou, taking an extra turn after this one.
Attack with Phantom Steed.
Phantom Steed triggers, creating a token copy of Eternal Witness that is tapped and attacking.
Eternal Witness enters, returning Capture of Jingzhou from your graveyard to your hand.
Pass the turn.
Repeat.

Result

Infinite turns; Lock

Variations

Cheaper, tighter, alternate lines

Time Warp and Temporal Manipulation are direct substitutes for Capture of Jingzhou if a cheaper extra-turn spell is preferred, though all sit at five mana so the swap is lateral. Reconnaissance or Tetsuko Umezawa, Fugitive can replace the unblockable prerequisite in green-blue lists that struggle to push Phantom Steed through — guaranteeing damage consistently is the combo's only structural weak point.
