Rukarumel, Biologist

Bog Glider

Dryad Arbor

Intruder Alarm

Hua Tuo, Honored Physician

How it works

1. Activate Bog Glider by tapping it and sacrificing Dryad Arbor.
2. Holding priority, activate Hua Tuo by tapping it, putting Dryad Arbor on top of your library from your graveyard.
3. Resolve the Bog Glider ability, searching your library for Dryad Arbor and putting it onto the battlefield.
4. When Dryad Arbor enters the battlefield, Intruder Alarm triggers, untapping all creatures.
5. Repeat.

This clever loop hinges entirely on Rukarumel, Biologist, whose static ability ensures that every creature card you own—including Dryad Arbor sitting in your graveyard—is treated as a Sliver in addition to its other types. Because Dryad Arbor counts as a Sliver, Bog Glider’s search ability can fetch it directly from your library when you sacrifice it. To sustain the loop, Hua Tuo, Honored Physician actively recycles Dryad Arbor right back onto the top of your library in response, ensuring it's always ready to be found again. Every time Dryad Arbor successfully enters the battlefield, Intruder Alarm triggers to untap all your creatures—including Bog Glider and Hua Tuo—allowing you to repeat the entire process indefinitely.
