Romana II + Overlord of the Hauntwoods + Retreat to Coralhelm + Spelunking

Romana II

Overlord of the Hauntwoods

Retreat to Coralhelm

Spelunking

How it works

1. Cast Overlord of the Hauntwoods by paying 3.
2. When Overlord of the Hauntwoods enters the battlefield, it triggers, creating am untapped Everywhere land token due to Spelunking.
3. When the Everywhere token enters the battlefield, Retreat to Coralhelm triggers, untapping Romana II.
4. Activate the Everywhere token by tapping it, adding 1.
5. Activate Romana II by paying 1 and tapping it, creating an untapped copy of the Everywhere token due to Spelunking.
6. Repeat from step 3.

This clever setup transforms a simple land-copying engine into an infinite resource generator by weaving together card types and passive battlefield modifiers. When Overlord of the Hauntwoods enters the battlefield—whether cast normally or via Spelunking—it creates a token copy of the land Everywhere, which counts as every basic land type. Thanks to Spelunking's static ability ensuring your lands enter untapped, that Everywhere token immediately triggers Retreat to Coralhelm to untap Romana II. You can then tap Romana II alongside the Everywhere token to fuel her ability, using her tap-and-pay cost to copy the very token that just entered. Repeating this loop feeds infinite landfall triggers directly back into Retreat to Coralhelm, letting you generate an endless army of Everywhere tokens while churning through your library with scry effects.
