Riku of Two Reflections + Narset's Reversal + Time Walk

Riku of Two Reflections

Narset's Reversal

Time Walk

How it works

1. Cast Time Walk by paying 1.
2. Riku's first ability triggers - choose not to pay.
3. Holding priority, cast Narset's Reversal by paying , targeting Time Walk.
4. Riku's first ability triggers, causing you to pay to copy Narset's Reversal, with the copy targeting the original Narset's Reversal.
5. Resolve the copy of Narset's Reversal, copying the original Narset's Reversal targeting Time Walk, and returning the original Narset's Reversal to your hand.
6. Resolve the copy of Narset's Reversal created in step 5, copying Time Walk and returning the original Time Walk to your hand.
7. Resolve Time Walk, causing you to take an extra turn after this one.
8. Repeat each turn.

This Vintage-legal loop hinges on carefully orchestrating Narset's Reversal and Riku of Two Reflections to endlessly recycle Time Walk. By using Riku of Two Reflections to copy Narset's Reversal while it targets the original Time Walk, you can bounce both spells back to your hand instead of letting them resolve permanently. This lets you recast Time Walk every single turn, securing infinite turns while Riku of Two Reflections and Narset's Reversal continuously catch and replay each other's effects.
