Deeproot Pilgrimage + Kiora's Follower + Chameleon, Master of Disguise

Deeproot Pilgrimage

Kiora's Follower

Chameleon, Master of Disguise

How it works

1. Activate Kiora's Follower by tapping it, targeting Chameleon.
2. Deeproot Pilgrimage triggers, creating a 1/1 Merfolk creature token.
3. Resolve the Kiora's Follower ability, untapping Chameleon.
4. Activate Chameleon by tapping it, targeting Kiora's Follower.
5. Deeproot Pilgrimage triggers, creating a 1/1 Merfolk creature token.
6. Resolve the Chameleon ability, untapping Kiora's Follower.
7. Repeat.

This clever loop turns a pair of mutually supportive creatures into an endless army by exploiting their untap abilities in tandem. While Kiora's Follower and Chameleon, Master of Disguise take turns tapping to untap one another back and forth, Deeproot Pilgrimage watches quietly from the enchantment zone and rewards every single one of those taps with a fresh hexproof token. Because Chameleon enters as a copy of a creature you control (such as Kiora's Follower itself), it shares the exact same mechanical utility to keep the engine spinning indefinitely.
