Springheart Nantuko + Dryad Arbor + Mana Reflection + Thousand-Year Elixir

Springheart Nantuko

Dryad Arbor

Mana Reflection

Thousand-Year Elixir

How it works

1. Play a land. When the land enters, Springheart Nantuko triggers, causing you to pay 1 to create a token copy of Dryad Arbor.
2. When the Dryad Arbor token enters, Springheart Nantuko triggers. Holding priority, activate the Dryad Arbor token by tapping it, adding due to Mana Reflection.
3. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Dryad Arbor.
4. Repeat from step 2.
