4. Reoslve the Tireless Provisioner trigger, creating a Treasure token.
5. Resolve the Retreat to Coralhelm trigger, untapping Romana II.
6. Activate the Treasure by tapping and sacrificing it, adding 1.
7. Activate Romana II by paying 1 and tapping it, creating a tapped copy of the Mutavault token.
8. Repeat from step 3.
