Blossoming Tortoise + Dryad Arbor + Infinite Reflection + Blasting Station

Blossoming Tortoise

Dryad Arbor

Infinite Reflection

Blasting Station

How it works

1. Play Dryad Arbor.
2. When Dryad Arbor enters the battlefield as a copy of Blossoming Tortoise due to Infinite Reflection, it and Blasting Station trigger.
3. Resolve the Blasting Station trigger, untapping it.
4. Holding priority, activate Blasting Station by tapping it and sacrificing Dryad Arbor, dealing 1 damage to any target.
5. Resolve the Dryad Arbor trigger from step 2, causing you to mill three cards and return Dryad Arbor from your graveyard to the battlefield.
6. Repeat from step 2.

This clever loop centers on Infinite Reflection enchanting a copied creature so that every new creature you cast enters the battlefield as a copy of it. By leveraging Dryad Arbor as a land that naturally enters as a creature, you can exploit this aura to instantly replicate Blossoming Tortoise's entry triggers. As these Tortoise copies flood the board, they constantly trigger Blasting Station to untap itself, allowing you to continually sacrifice the Dryad Arbor copy for infinite damage.
