What must be in place

Stone-Seeder Hierophant does not have summoning sickness.

How to execute it

  1. Activate any number of other lands by tapping them, adding at least {4}{C}.
  2. Activate Need for Speed by sacrificing a land except Mirrorpool.

  4. Activate Mirrorpool's third ability by paying {4}{C}, tapping and sacrificing it, creating a token copy of Lumra.
  5. Put the Lumra token into your graveyard due to the legend rule.
  6. The Lumra token's enters-the-battlefield ability triggers, causing you to mill four cards and return all land cards from your graveyard to the battlefield tapped.

  8. Resolve the first trigger, untapping Stone-Seeder Hierophant.
