The 3 combo pieces

How to execute it

  1. Cast Clockspinning with buyback by paying {3}{U}, targeting Gonti's Aether Heart.
  2. Vesuvan Duplimancy triggers, creating a token copy of Gonti's Aether Heart that isn't legendary.
  3. When the token Gonti's Aether Heart enters the battlefield, each Gonti's Aether Heart you control triggers, causing you to get {E}{E} for each Gonti's Aether Heart you control.
  4. Resolve Clockspinning, returning it to your hand.
  5. If you have less than eight {E}, repeat from step 1 one additional time.
  6. Activate a Gonti's Aether Heart token by paying eight {E} and exiling it, causing you to take an extra turn after this one.
  7. Repeat each turn.
