Prototype Portal
Ugin's Nexus
Atog

Requires
Prototype Portal must be on the battlefield. Ugin's Nexus must be in exile (exiled by Prototype Portal). Atog must be on the battlefield. Mana needed: 5 each turn
Steps
  1. Activate Prototype Portal by paying 5 and tapping it, creating a token copy of Ugin's Nexus.
  2. Activate Atog by sacrificing the Ugin's Nexus token.
  3. The Ugin's Nexus token is exiled instead of being put into your graveyard, causing you to take an extra turn after this one.

  5. Repeat each turn.
Results
