Resolve the Simic Growth Chamber trigger, returning it from the battlefield to your hand.
Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Icetill Explorer.
Because of the additional Icetill Explorer token, you can play an additional land this turn.
Repeat.
This clever loop relies on the quiet mastery of **The Wandering Minstrel**, whose static ability ensures that **Simic Growth Chamber** enters the battlefield untapped, ready to tap for mana before its bounce trigger forces it back to your hand. Meanwhile, **Icetill Explorer** plays a double role: its passive ability grants you the crucial extra land drop needed to replay the returned bounceland each iteration, while its landfall trigger mills cards to fuel the engine. With **Springheart Nantuko** bestowed onto the Explorer, every single land drop triggers the enchantment to pay for and copy the creature, compounding your token army and landfall triggers infinitely.
