The 3 combo pieces

What must be in place

You have enough mana to cast Walk the Aeons each turn.

How to execute it

  1. Cast Walk the Aeons by paying its mana cost, causing you to take an extra turn after this one.
  2. Move to your next turn.
  3. At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Ardent Elementalist.
  4. When the Ardent Elementalist token enters the battlefield, it triggers, returning Walk the Aeons from your graveyard to your hand.
  5. Repeat.
