Emry, Lurker of the Loch + Ugin's Nexus + Isochron Scepter + Pull from Eternity + Phantom Train

Emry, Lurker of the Loch

Ugin's Nexus

Isochron Scepter

Pull from Eternity

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Ugin's Nexus
2. When Ugin's Nexus is sacrificed, it is exiled instead of being put into your graveyard, causing you to take an extra turn after this one.
3. Move to your next turn.
4. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of Pull from Eternity without paying its mana cost.
5. Resolve Pull from Eternity, putting Ugin's Nexus from exile into your graveyard.
6. Activate Emry by tapping it, targeting Ugin's Nexus.
7. Cast Ugin's Nexus from your graveyard by paying 5.
8. Repeat.

This intricate loop seizes control of the timeline by weaponizing Ugin's Nexus, turning its replacement effect into a tool for endless extra turns. Since Ugin's Nexus exiles itself to grant you that extra turn, Phantom Train provides the initial sacrifice, while Isochron Scepter—imprinting Pull from Eternity—snatches the Nexus right back out of exile and drops it into your graveyard. From there, Emry, Lurker of the Loch steps in to let you recast the artifact from your graveyard, resetting the whole cycle so you can chain infinite turns together.
