Double Vision + Venser, Shaper Savant + Naban, Dean of Iteration + Time Warp

Double Vision

Venser, Shaper Savant

Naban, Dean of Iteration

Time Warp

How it works

1. Cast Time Warp by paying 3.
2. Double Vision triggers, copying Time Warp.
3. Holding priority, cast Venser by paying 2.
4. When Venser enters the battlefield, it triggers twice, returning itself and the original Time Warp to your hand from the battlefield and stack respectively.
5. Resolve the copy of Time Warp, causing you to take an extra turn after this one.
6. Repeat each turn.

This engine hinges on the clever exploitation of the stack and your own triggers to lock down infinite turns. By kicking things off with Time Warp, you let Double Vision double up your spellcasting momentum. Meanwhile, Naban, Dean of Iteration serves as a critical multiplier, doubling Venser, Shaper Savant's entry trigger so you can conveniently return both Venser and the original Time Warp right back to your hand for the next cycle.
