Activate Salvaging Station by tapping it, returning The Last Ride from your graveyard to the battlefield.
When The Last Ride enters, Kolodin triggers, causing The Last Ride to become an artifact creature until end of turn.
Activate Altar of Dementia by sacrificing The Last Ride.
When The Last Ride dies, Salvaging Station triggers, untapping Salvaging Station.
Resolve the Altar of Dementia ability.
Repeat.
This clever loop turns graveyard recycling into a mill engine by utilizing Salvaging Station to continuously resurrect The Last Ride, which slips right back into the graveyard every time it's fed to Altar of Dementia. Kolodin, Triumph Caster makes this recursion lethal and immediate by instantly transforming The Last Ride into an active artifact creature the moment it enters the battlefield, bypassing any traditional crewing requirements. With Salvaging Station untapping itself from the resulting death trigger, you have all the necessary fuel to infinitely mill your opponents.
