Tatyova, Benthic Druid + Doppelgang + Mystic Sanctuary

Tatyova, Benthic Druid

Doppelgang

Mystic Sanctuary

How it works

1. Cast Doppelgang by paying 12, 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.
2. When the tokens enter the battlefield untapped, each Mystic Sanctuary token triggers, and Tatyova 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 Tatyova triggers, causing you to draw that many cards, including Doppelgang with the first draw, and gain that much life.
5. Activate the four Mystic Sanctuary tokens by tapping them, adding .
6. Activate ten of the other permanent tokens created in step 1 by tapping them, adding at least 9.
7. Repeat.
