Springheart Nantuko + Dryad Arbor + Hammer of Purphoros + Caged Sun

Springheart Nantuko

Dryad Arbor

Hammer of Purphoros

Caged Sun

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 .
3. Caged Sun triggers, adding .
4. Resolve the Springheart Nantuko trigger, causing you to pay 1 to create a token copy of Dryad Arbor.
5. Repeat from step 2.

This clever loop turns the humble Dryad Arbor into an unstoppable engine by leveraging Springheart Nantuko's landfall ability to continually clone it as a creature-land. Because Caged Sun doubles the green mana produced when you tap that Dryad Arbor for mana, it helps fund the recurring {1}{G} cost required to keep the copying chain going with each new land arrival. Meanwhile, Hammer of Purphoros quietly ensures that your massive horde of tokens isn't caught waiting around, granting them immediate haste the moment they materialize.
