Bog Glider + Dryad Arbor + Retreat to Coralhelm + Mortuary + Arcane Adaptation

Bog Glider

Dryad Arbor

Retreat to Coralhelm

Mortuary

Arcane Adaptation

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 from step 1, searching your library for Dryad Arbor and putting it onto the battlefield.
4. When Dryad Arbor enters the battlefield, Retreat to Coralhelm triggers, untapping Bog Glider.
5. Repeat.

This clever loop turns Bog Glider into a relentless recruiter by exploiting the unique nature of Dryad Arbor, which pulls double duty as both a land and a creature. With Arcane Adaptation naming "Mercenary" to ensure Bog Glider's search capability can always find it, sacrificing the Arbor to fetch itself triggers Mortuary to quietly tuck it back onto the top of your library instead of letting it stay in the graveyard. Every time Dryad Arbor re-enters the battlefield, Retreat to Coralhelm's landfall ability untaps Bog Glider to instantly restart the cycle, generating an infinite parade of land drops and creature sacrifices.
