Narset, Enlightened Master
Mirror of Fate
Scrabbling Claws
Karn's Temporal Sundering

Requires
Narset, Enlightened Master must be on the battlefield. Mirror of Fate must be on the battlefield. Scrabbling Claws must be on the battlefield. Karn's Temporal Sundering must be in exile. Narset does not have summoning sickness. An opponent is unable to block and kill Narset. You have at least three other cards in exile.
Steps
  1. Activate Mirror of Fate by tapping and sacrificing it.
  2. Holding priority, activate Scrabbling Claws by tapping it, causing you to exile Mirror of Fate from your graveyard.
  3. Resolve the Mirror of Fate ability, choosing itself, Karn's Temporal Sundering and three to five other cards, then exiling your library and putting the chosen cards on top, ensuring Karn's Temporal Sundering and Mirror of Fate are the topmost cards.
  4. Declare Narset as an attacker.
  5. Narset triggers, exiling the top four cards of your library and allowing you to cast them from exile this turn without paying their mana costs.
  6. Move to your postcombat main phase.
  7. Cast Karn's Temporal Sundering from exile without paying its mana cost, causing you to take an extra turn after this one and exile Karn's Temporal Sundering.
  8. Cast Mirror of Fate from exile without paying its mana cost.
  9. Repeat each turn.
