2. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create two token copies of Mutable Explorer.
3. When the Mutable Explorer tokens enter, they trigger.
4. Resolve the first Mutable Explorer trigger, creating two Mutavault land tokens that enters tapped.
5. When the Mutavault tokens enter, Springheart Nantuko and Tireless Provisioner each trigger twice.
6. Resolve the Tireless Provisioner triggers, creating two Treasure tokens.
7. Holding priority, activate the Treasures by tapping them, adding 1
8. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Mutable Explorer.
