Springheart Nantuko + Dryad Arbor + Urabrask the Hidden + Mirari's Wake

Springheart Nantuko

Dryad Arbor

Urabrask the Hidden

Mirari's Wake

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. Mirari's Wake 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 brilliant engine uses Springheart Nantuko's landfall ability to repeatedly copy Dryad Arbor, which conveniently counts as both a creature and a land to perpetually restart the loop. As each new Dryad Arbor token enters the battlefield, Mirari's Wake doubles the green mana you generate by tapping those tokens for mana to pay for the Nantuko's replication cost. Meanwhile, Urabrask the Hidden ensures that your massive horde of newly created creature tokens immediately enters the battlefield tapped, keeping the sequence orderly while you flood the board with an infinite number of lands and creatures.
