How it works
Play a land.
When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create a token copy of Springbloom Druid.
When the Springbloom Druid token enters, it triggers, causing you to sacrifice a land, then search your library for two basic lands and put them onto the battlefield tapped.
When the Forest and other basic land enter, Stone-Seeder Hierophant and Springheart Nantuko trigger twice.
Resolve a Stone-Seeder Hierophant trigger, untapping it.
Holding priority, activate Stone-Seeder Hierophant by tapping it, untapping a land that can tap to produce .
Activate the land by tapping it, adding at least .
Repeat steps 5 through 7 for the remaining Stone-Seeder Hierophant trigger.
Resolve the first Springheart Nantuko trigger, choosing not to pay and creating a 1/1 Insect creature token.
Resolve the second Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Springbloom Druid.
Repeat from step 3 until your library contains no basic lands.
