Springbloom Druid + Springheart Nantuko + Stone-Seeder Hierophant

Prerequisites

You have a land card in hand. You are able to play a land this turn. You control a land that can tap to produce at least {G} and/or have a basic Forest in your library.

Steps

1. Play a land.
2. When the land enters, Springheart Nantuko triggers, causing you to pay {1}{G} to create a token copy of Springbloom Druid.
3. 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.
4. When the Forest and other basic land enter, Stone-Seeder Hierophant and Springheart Nantuko trigger twice.
5. Resolve a Stone-Seeder Hierophant trigger, untapping it.
6. Holding priority, activate Stone-Seeder Hierophant by tapping it, untapping a land that can tap to produce {G}.
7. Activate the land by tapping it, adding at least {G}.
8. Repeat steps 5 through 7 for the remaining Stone-Seeder Hierophant trigger.
9. Resolve the first Springheart Nantuko trigger, choosing not to pay and creating a 1/1 Insect creature token.
10. Resolve the second Springheart Nantuko trigger, causing you to pay {1}{G} to create a token copy of Springbloom Druid.
11. Repeat from step 3 until your library contains no basic lands.
