How it works

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, causing it to become a copy of Aftermath Analyst until end of turn.
4. Activate Shifting Woodland by paying 3 and sacrificing it, returning it and all other land cards from your graveyard to the battlefield tapped.
5. When the lands enter the battlefield, Stone-Seeder Hierophant triggers that many times.
6. Resolve the first trigger, untapping Stone-Seeder Hierophant.
7. Activate Stone-Seeder Hierophant by tapping it, untapping a land.
8. Repeat from step 5 for each remaining trigger.
9. Activate any number of lands by tapping them, adding at least 5.
10. Repeat.
11. Resolve all Sylvan Safekeeper abilities.
