When Dakmor Salvage enters, Scute Swarm 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 Scute Swarm 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, Scute Swarm triggers.
Repeat from step 4.
This engine transforms the simple act of playing a land into an endless loop of value, powered by some brilliant synergy between your graveyard and hand. Every time Dakmor Salvage enters the battlefield, it triggers Scute Swarm to make a token, which in turn triggers Kodama of the East Tree to put Dakmor Salvage right back onto the battlefield from your hand. You can sacrifice that very same land to Sylvan Safekeeper to protect your creatures, which feeds The Gitrog Monster's draw trigger—allowing you to replace the draw with Dakmor Salvage's dredge ability to keep your hand perpetually stocked.
