2. Efreet Flamepainter triggers, causing you to cast Time Walk from your graveyard without paying its mana cost.
3. Resolve Time Walk, 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 Time Walk from exile into your graveyard.
6. Repeat each turn.
