Springheart Nantuko + Dryad Arbor + Mana Reflection + Mass Hysteria

Springheart Nantuko

Dryad Arbor

Mana Reflection

Mass Hysteria

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 fascinating loop turns a modest land drop into an engine of endless replication by wrapping Springheart Nantuko around a land-creature like Dryad Arbor. Because Mass Hysteria grants haste to the newly created Dryad Arbor tokens, and Mana Reflection doubles their mana production upon tapping, each iteration generates more than enough green mana to fund the next landfall trigger. As you repeat this cycle, you produce an endless army of tapped Forest tokens alongside infinite enters-the-battlefield and landfall triggers.
