When Dakmor Salvage enters, Chocobo Racetrack and Kodama trigger.
Resolve the Kodama trigger, choosing to put nothing onto the battlefield.
Holding priority, activate Trenching Steed 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 Trenching Steed ability
Resolve the Chocobo Racetrack 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, Chocobo Racetrack triggers.
Repeat from step 4.
This elaborate loop turns the humble act of replaying a land into a self-sustaining engine of creation and card draw. By combining Trenching Steed as a reliable sacrifice outlet with Chocobo Racetrack, every iteration triggers a flurry of token generation and landfall bonuses. Meanwhile, The Gitrog Monster converts the constant flow of lands entering your graveyard into fresh cards, cleverly substituting those draws with Dakmor Salvage’s dredge ability to keep the cycle perpetually fueled. Finally, Kodama of the East Tree watches the ensuing token entries and effortlessly slips Dakmor Salvage right back onto the battlefield to start the whole dance anew.
