Springheart Nantuko + Selesnya Sanctuary + Dryad of the Ilysian Grove + Horizon Explorer

Springheart Nantuko

Selesnya Sanctuary

Dryad of the Ilysian Grove

Horizon Explorer

How it works

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

This clever loop relies on Horizon Explorer's static ability to keep Selesnya Sanctuary entering the battlefield untapped, transforming what is normally a slow bounce land into an engine for infinite triggers. Whenever Selesnya Sanctuary hits the board, its own enters-the-battlefield trigger returns it safely to your hand while Springheart Nantuko uses its landfall ability to churn out copies of Dryad of the Ilysian Grove. Because Dryad of the Ilysian Grove grants you the crucial extra land drop you need each turn, you can continuously replay Selesnya Sanctuary to restart the entire cycle.
