Springheart Nantuko + Tiller Engine + Selesnya Sanctuary + Wayward Swordtooth

Springheart Nantuko

Tiller Engine

Selesnya Sanctuary

Wayward Swordtooth

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 Wayward Swordtooth.
6. Because of the additional Wayward Swordtooth token, you can play an additional land this turn.
7. Repeat.

This delightful loop turns the humble bounce-land Selesnya Sanctuary into a self-sustaining engine by exploiting the synergy between landfall and extra land drops. When Selesnya Sanctuary enters the battlefield, it triggers its own bounce ability alongside Tiller Engine, which instantly untaps the land, and Springheart Nantuko, which uses the landfall trigger to copy a creature for a small mana payment. By tapping Selesnya Sanctuary for mana before it returns to your hand, you fund the copy cost to multiply your permanents, while Wayward Swordtooth provides the essential extra land drop each turn needed to keep replaying the Sanctuary and repeating the cycle.
