Springheart Nantuko + Overlord of the Hauntwoods + Elspeth, Storm Slayer + Horizon Explorer

Springheart Nantuko

Overlord of the Hauntwoods

Elspeth, Storm Slayer

Horizon Explorer

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 Horizon Explorer each trigger twice.
4. Resolve all Horizon Explorer 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.

This delightful loop begins when Overlord of the Hauntwoods attacks, triggering its ability to generate Everywhere land tokens. Because Elspeth, Storm Slayer is doubling all token creation, you actually receive two Everywhere tokens, which instantly triggers Horizon Explorer twice to keep your mana sources flowing and untapped. Meanwhile, those landfalls feed Springheart Nantuko—bestowed upon your creature—which uses the floating mana from tapping your new Everywhere tokens to pay for its landfall cost. Thanks to Elspeth, Storm Slayer doubling everything once more, you reap an exponential horde of token copies and resources that quickly overwhelms the battlefield.
