Jin-Gitaxias, Progress Tyrant + Venser, Shaper Savant + Naban, Dean of Iteration + Time Warp

Jin-Gitaxias, Progress Tyrant

Venser, Shaper Savant

Naban, Dean of Iteration

Time Warp

How it works

1. Cast Time Warp by paying 3.
2. Jin-Gitaxias 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 magnificent engine achieves infinite turns by exploiting a recursive casting loop that continuously recycles your resources. When you cast Time Warp, Jin-Gitaxias, Progress Tyrant steps in to double your spellcasting output by copying it for free. To keep the loop going indefinitely, you drop Venser, Shaper Savant with flash, whose entry triggers twice thanks to Naban, Dean of Iteration's amplification; this double-bounce allows you to scoop both the original Time Warp and Venser right back to your hand. As an added bonus, Jin-Gitaxias's passive ability completely shuts down your opponents by automatically countering the first artifact, instant, or sorcery spell they try to cast.
