The 3 combo pieces

What must be in place

You control at least two additional Islands.
You control at least three additional permanents that enter the battlefield untapped and can collectively tap to produce at least {2}{G}.

How to execute it

  1. Cast Doppelgang by paying {12}{G}{U}, creating four token copies of Mystic Sanctuary and three other permanents that enter the battlefield untapped and can collectively tap to produce at least {2}{G}.
  2. When the tokens enter the battlefield untapped, each Mystic Sanctuary token triggers, and Aesi triggers for each land token that entered the battlefield.
  3. Resolve all Mystic Sanctuary triggers, putting Doppelgang on top of your library from your graveyard.
  4. Resolve all Aesi triggers, causing you to Doppelgang, and optionally allowing you to draw a card for each remaining trigger.
  5. Activate the four Mystic Sanctuary tokens by tapping them, adding {U}{U}{U}{U}.
  6. Activate ten of the other permanent tokens created in step 1 by tapping them, adding at least {9}{G}.
  7. Repeat.
