Bog Glider + Dryad Arbor + Intruder Alarm + Conspiracy + Hua Tuo, Honored Physician

Bog Glider

Dryad Arbor

Intruder Alarm

Conspiracy

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 relies on Conspiracy to rewrite the rules of your deck, choosing "Mercenary" so that every creature card you own—including Dryad Arbor—fits the criteria for Bog Glider's search ability. By sacrificing Dryad Arbor as part of Bog Glider's activation, you send the land-creature to the graveyard just in time for Hua Tuo, Honored Physician to tap and place it right back on top of your library. When Bog Glider's search resolves and puts Dryad Arbor back onto the battlefield, Intruder Alarm sees the new arrival and triggers to untap all your creatures, letting you repeat the entire process indefinitely.
