Springheart Nantuko + Overlord of the Hauntwoods + Tiller Engine + Elspeth, Storm Slayer

Springheart Nantuko

Overlord of the Hauntwoods

Tiller Engine

Elspeth, Storm Slayer

How it works

1. Declare Overlord of the Hauntwoods as an attacker.
2. Overlord of the Hauntwoods triggers, creating two tapped Everywhere land tokens.
3. When the Everywhere tokens enter the battlefield, Springheart Nantuko and Tiller Engine each trigger twice.
4. Resolve all Tiller Engine triggers, untapping the lands.
5. Holding priority, activate the Everywhere tokens by tapping them, adding 1.
6. Resolve the first Springheart Nantuko trigger, choosing not to pay and creating two 1/1 Insect creature tokens.
7. Resolve the second Springheart Nantuko trigger, causing you to pay 1 to create two token copies of Overlord of the Hauntwoods.
8. When the Overlord of the Hauntwoods tokens enters the battlefield, they trigger.
9. Resolve the first trigger, creating two tapped Everywhere land tokens.
10. Repeat from step 3.
