Springheart Nantuko + Spelunking + Selesnya Sanctuary + Icetill Explorer

Springheart Nantuko

Spelunking

Selesnya Sanctuary

Icetill Explorer

How it works

1. Play Selesnya Sanctuary. When it enters untapped due to Spelunking, 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 intricate loop turns the humble Selesnya Sanctuary into an engine of exponential growth, entirely fueled by Spelunking overriding the bouncyland's natural hesitation to enter tapped. With Spelunking ensuring everything enters ready for action, playing Selesnya Sanctuary lets you bounce it right back to your hand while triggering Springheart Nantuko to continuously copy Icetill Explorer. Each newly minted copy of Icetill Explorer grants you the extra land drop needed to replay the Sanctuary, while Icetill Explorer's own passive ability allows you to replay it endlessly from your graveyard or hand if things shift.
