When Dakmor Salvage enters, Springheart Nantuko and Kodama trigger.
Resolve the Kodama trigger, choosing to put nothing onto the battlefield.
Holding priority, activate Sylvan Safekeeper by sacrificing Dakmor Salvage.
The Gitrog Monster's second ability triggers, causing you to mill two cards and return Dakmor Salvage from your graveyard to your hand.
If a land was milled this way, The Gitrog Monster's second ability triggers, causing you to draw a card.
Resolve the Sylvan Safekeeper ability
Resolve the Springheart Nantuko trigger, creating a token.
When the token enters the battlefield, Kodama triggers, putting Dakmor Salvage from your hand onto the battlefield.
When Dakmor Salvage enters the battlefield, Springheart Nantuko triggers.
Repeat from step 4.
This ingenious loop leverages Kodama of the East Tree as an engine to constantly redeploy Dakmor Salvage whenever a token enters the battlefield. Springheart Nantuko provides those tokens via its landfall ability, while Sylvan Safekeeper offers a reliable outlet to sacrifice the land on demand. Meanwhile, The Gitrog Monster watches over the entire operation, turning every self-mill from Dakmor Salvage's dredge mechanic into a fresh card drawn and keeping the momentum going.
