When Venser enters the battlefield, it triggers twice, returning itself and the original Temporal Manipulation to your hand from the battlefield and stack respectively.
Resolve the copy of Temporal Manipulation, causing you to take an extra turn after this one.
Repeat each turn.
This mesmerizing loop centers around casting Temporal Manipulation as your first spell of the turn, allowing Double Vision to generously duplicate it while Elesh Norn, Mother of Machines doubles up your entry triggers. Dropping Venser, Shaper Savant into the mix leverages that doubled trigger to scoop both Venser himself back to your hand and bounce the original Temporal Manipulation right off the stack, safely resetting your engine. With your extra turn secured by the copied spell, you can simply repeat this sequence indefinitely to lock down the game and dictate every step forward.
