Timesifter
Draco
Isochron Scepter
Pull from Eternity
Academy Ruins

Requires
Timesifter must be on the battlefield. Draco must be in exile. Isochron Scepter must be on the battlefield. Pull from Eternity must be in exile (exiled by Isochron Scepter). Academy Ruins must be on the battlefield. Mana needed: 3 each turn
Steps
  1. Activate Isochron Scepter by paying 2 and tapping it, casting a copy of Pull from Eternity without paying its mana cost.
  2. Resolve the copy of Pull from Eternity, putting Draco into your graveyard from exile.
  3. Activate Academy Ruins' second ability by paying 1 and tapping it, putting Draco on top of your library from your graveyard.
  4. Move to the next turn.
  5. At the beginning of that turn's upkeep, Timesifter triggers, exiling the top card of each player's library, and causing you to take an extra turn after this one due to exiling the highest mana value card.
  6. Repeat.
Results
Infinite turns.
