Springheart Nantuko + Stone-Seeder Hierophant + Selesnya Sanctuary + Wayward Swordtooth

Springheart Nantuko

Stone-Seeder Hierophant

Selesnya Sanctuary

Wayward Swordtooth

How it works

1. Play Selesnya Sanctuary. When it enters, Stone-Seeder Hierophant, Selesnya Sanctuary and Springheart Nantuko trigger.
2. Resolve the Stone-Seeder Hierophant trigger, untapping it.
3. Holding priority, activate Stone-Seeder Hierophant by tapping it, untapping Selesnya Sanctuary.
4. Activate Selesnya Sanctuary by tapping it, adding .
5. Resolve the Selesnya Sanctuary trigger, returning it from the battlefield to your hand.
6. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Wayward Swordtooth.
7. Because of the additional Wayward Swordtooth token, you can play an additional land this turn.
8. Repeat.

This infinite loop turns the bounce mechanic of Selesnya Sanctuary into a self-sustaining engine by leveraging the extra land drop granted by Wayward Swordtooth. Each time you replay the Sanctuary, its landfall trigger pairs with Springheart Nantuko to generate a token copy of the Swordtooth, further expanding your land-playing capacity while triggering Stone-Seeder Hierophant. The Hierophant's activated ability acts as the linchpin, untapping the Sanctuary so it can generate mana and bounce itself right back to your hand to repeat the cycle endlessly.
