Springheart Nantuko + Tiller Engine + Selesnya Sanctuary + Dryad of the Ilysian Grove

Springheart Nantuko

Tiller Engine

Selesnya Sanctuary

Dryad of the Ilysian Grove

How it works

1. Play Selesnya Sanctuary. When it enters, Tiller Engine, Selesnya Sanctuary and Springheart Nantuko trigger.
2. Resolve the Tiller Engine trigger, untapping Selesnya Sanctuary.
3. Holding priority, activate Selesnya Sanctuary by tapping it, adding .
4. Resolve the Selesnya Sanctuary trigger, returning it from the battlefield to your hand.
5. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Dryad of the Ilysian Grove.
6. Because of the additional Dryad of the Ilysian Grove token, you can play an additional land this turn.
7. Repeat.

This loop turns Selesnya Sanctuary into a self-sustaining engine by exploiting its mandatory bounce trigger alongside Tiller Engine's untap ability. Because Dryad of the Ilysian Grove grants extra land drops and makes your lands every basic type, you can repeatedly replay the returned Sanctuary, while Springheart Nantuko uses each landfall event to pay its bestow cost and mass-produce endless token copies of your Dryad.
