What must be in place

There are at least four card types among cards in your graveyard.

How to execute it

  1. Activate Sylvan Safekeeper by sacrificing any land except Shifting Woodland.
  2. Repeat step 1 until you control no other lands except Shifting Woodland.
  3. Activate Shifting Woodland's second ability by paying {2}{G}{G}, causing it to become a copy of Aftermath Analyst until end of turn.
  4. Activate Shifting Woodland by paying {3}{G} and sacrificing it, returning it and all other land cards from your graveyard to the battlefield tapped.
  5. When the lands enter the battlefield, Tiller Engine triggers that many times, untapping the lands.
