Efreet Flamepainter + Isochron Scepter + Pull from Eternity + Temporal Mastery

Efreet Flamepainter

Isochron Scepter

Pull from Eternity

Temporal Mastery

How it works

1. Deal combat damage to an opponent using Efreet Flamepainter.
2. Efreet Flamepainter triggers, causing you to cast Temporal Mastery from your graveyard without paying its mana cost.
3. Resolve Temporal Mastery, causing you to take an extra turn after this one and exile it.
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 Temporal Mastery from exile into your graveyard.
6. Repeat each turn.

This brilliant loop bends time to your will by taking advantage of the exile-replacement clause on Temporal Mastery, turning what is normally a one-way trip into a renewable resource. Once Isochron Scepter has imprinted Pull from Eternity, you can fire off the spell during your extra turns to scoop that exiled Temporal Mastery right back into your graveyard. From there, Efreet Flamepainter's double strike and combat-damage trigger swoop in to cast the time-walk spell straight from the graveyard for free. Repeat this cycle every turn, and you'll easily lock opponents out of the game while taking all the time you need.
