Double Vision + Venser, Shaper Savant + Yarok, the Desecrated + Time Warp

Double Vision

Venser, Shaper Savant

Yarok, the Desecrated

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.
