Thassa, Deep-Dwelling blinks Eternal Witness at the end of each turn, which returns Capture of Jingzhou from the graveyard to hand in time to cast it on the extra turn. The loop asks for 3UU every cycle, so ramp density matters — this lives in Simic goodstuff or dedicated extra-turns shells that already run Eternal Witness as an engine piece.

Variations

Cheaper, tighter, alternate lines

Time Warp and Temporal Manipulation are direct swaps for Capture of Jingzhou at the same 3UU cost; Nexus of Fate is the graveyard-proof alternative if exile-based removal breaks the loop. Thassa can blink any creature with an ETB that recurs a spell — Eternal Witness is the standard choice, but Den Protector does the same job once it's face up.
