Springheart Nantuko + Selesnya Sanctuary + Horizon Explorer + Icetill Explorer

Springheart Nantuko

Selesnya Sanctuary

Horizon Explorer

Icetill 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 Icetill Explorer.
5. Because of the additional Icetill Explorer token, you can play an additional land this turn.
6. Repeat.

This clever loop turns the self-bouncing property of Selesnya Sanctuary into an endless engine by leveraging Horizon Explorer to ensure the land enters untapped every time. Each cycle is fueled by the mana you tap Selesnya Sanctuary for before it returns to your hand, providing the exact funds needed to pay for Springheart Nantuko's landfall trigger. That trigger copies whichever creature the Nantuko is bestowing, and when you choose Icetill Explorer, you continuously expand your land-play capacity and mill your library while churning out infinite creature tokens, landfalls, and entrance triggers.
