The Gitrog Monster + Kodama of the East Tree + Dakmor Salvage + Thaumatog + Eusocial Engineering

The Gitrog Monster

Kodama of the East Tree

Dakmor Salvage

Thaumatog

Eusocial Engineering

How it works

1. Play Dakmor Salvage.
2. When Dakmor Salvage enters, Eusocial Engineering and Kodama trigger.
3. Resolve the Kodama trigger, choosing to put nothing onto the battlefield.
4. Holding priority, activate Thaumatog by sacrificing Dakmor Salvage.
5. The Gitrog Monster's second ability triggers, causing you to mill two cards and return Dakmor Salvage from your graveyard to your hand.
6. If a land was milled this way, The Gitrog Monster's second ability triggers, causing you to draw a card.
7. Resolve the Thaumatog ability
8. Resolve the Eusocial Engineering trigger, creating a token.
9. When the token enters the battlefield, Kodama triggers, putting Dakmor Salvage from your hand onto the battlefield.
10. When Dakmor Salvage enters the battlefield, Eusocial Engineering triggers.
11. Repeat from step 4.

This clever loop turns Dakmor Salvage into a perpetual motion machine by leveraging its own dredge replacement effect alongside The Gitrog Monster's draw trigger. Whenever you sacrifice Dakmor Salvage to Thaumatog, The Gitrog Monster forces a dredge instead of a normal draw, seamlessly returning the land to your hand while filling your graveyard. Meanwhile, Eusocial Engineering provides a steady stream of landfall triggers whenever a land enters, which Kodama of the East Tree intercepts to immediately cheat Dakmor Salvage right back onto the battlefield.
