Springheart Nantuko + Dryad Arbor + Mana Reflection + Purphoros, Bronze-Blooded

Springheart Nantuko

Dryad Arbor

Mana Reflection

Purphoros, Bronze-Blooded

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.

This intricate loop uses Springheart Nantuko bestowed upon Dryad Arbor to infinitely replicate the land-creature, feeding you an endless stream of landfall triggers and creature tokens. As each new Dryad Arbor token hits the battlefield, Mana Reflection ensures its tap ability yields double the mana needed to pay for Springheart Nantuko's landfall creation cost, leaving you completely mana-neutral to keep the cycle going. Meanwhile, Purphoros, Bronze-Blooded quietly oversees the entire operation, granting haste to any other creatures you control so they can immediately make use of the resulting battlefield state.
