Prerequisites

• Toph, the First Metalbender on the battlefield
• Lithatog on the battlefield
• Biotransference on the battlefield

2. When you cast that spell, you lose 1 life and create a 2/2 artifact creature token
3. The earthbending creature enters as an artifact land creature due to Biotransference and Toph
4. When that creature enters, it earthbends, causing itself to become a land creature with haste, putting at least one +1/+1 counter on itself, and creating a delayed triggered ability
5. Activate Lithatog by sacrificing that creature
6. When that creature dies, the delayed ability from step 4 triggers, causing it to return to the battlefield tapped as an artifact land creature
7. Repeat from step 3 any number of times
8. Resolve all activated abilities from Lithatog
