Springheart Nantuko + Spelunking + Simic Growth Chamber + Icetill Explorer

Springheart Nantuko

Spelunking

Simic Growth Chamber

Icetill Explorer

How it works

1. Play Simic Growth Chamber. When it enters untapped due to Spelunking, Simic Growth Chamber and Springheart Nantuko trigger.
2. Holding priority, activate Simic Growth Chamber by tapping it, adding .
3. Resolve the Simic Growth Chamber 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 brilliant loop relies on Spelunking to completely bypass the drawback of Simic Growth Chamber, letting the bounce-land enter the battlefield untapped and instantly generate mana while triggering your landfall effects. Springheart Nantuko takes full advantage of these repeated land drops by turning every entry into a copied token, which is seamlessly sustained by Icetill Explorer allowing you to continuously replay the Simic Growth Chamber right back out of your hand. Because Icetill Explorer's own landfall ability and extra land drop stacking keep the engine churning, your token army and mana reserves grow without bound.
