Muldrotha, the Gravetide + Timestream Navigator + Isochron Scepter + Entomb

Muldrotha, the Gravetide

Timestream Navigator

Isochron Scepter

Entomb

How it works

1. Activate Timestream Navigator by paying 2, tapping it and putting it from the battlefield onto the bottom of your library, causing you to take an extra turn after this one.
2. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of Entomb without paying its mana cost.
3. Resolve Entomb, searching your library for Timestream Navigator and putting it into your graveyard.
4. Cast Timestream Navigator from your graveyard by paying 1.
5. Repeat each turn.

This hypnotic loop lets you bend time to your absolute will, locking down the game in a sequence of infinite extra turns. It all hinges on Isochron Scepter holding an Entomb, which acts as your reliable tutor to fetch Timestream Navigator right back into the graveyard whenever needed. From there, Muldrotha, the Gravetide provides the crucial permission to cast Timestream Navigator directly out of your graveyard turn after turn, completely bypassing the normal restrictions of the zone. You simply activate the Navigator to take another turn, tutor it away with the Scepter, replay it through Muldrotha, and repeat the cycle indefinitely.
