  3. Put the token Ugin's Nexus into exile due to the legend rule and the token's replacement effect, causing you to take an extra turn after this one.
  4. At the beginning of your end step, Phenomenon Investigators triggers, returning Ugin's Nexus from the battlefield to your hand and causing you to draw a card.
  5. Repeat during each of your turns.
