Bog Glider + Dryad Arbor + Intruder Alarm + Arcane Adaptation + Mortuary

Bog Glider

Dryad Arbor

Intruder Alarm

Arcane Adaptation

Mortuary

How it works

1. Activate Bog Glider by tapping it and sacrificing Dryad Arbor.
2. When Dryad Arbor dies, Mortuary triggers, 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 turns Bog Glider into a relentless engine by utilizing Arcane Adaptation to name "Mercenary," allowing the Glider to tutor up Dryad Arbor directly from your library. When you sacrifice Dryad Arbor to pay the cost, Mortuary immediately catches it on its way to the graveyard and places it right back on top of your library to be found again. Every time Dryad Arbor returns to the battlefield, Intruder Alarm triggers to untap all of your creatures, leaving Bog Glider fresh and ready to restart the entire cycle.
