Activate Salvaging Station by tapping it, returning Consulate Dreadnought from your graveyard to the battlefield.
When Consulate Dreadnought enters, Kolodin triggers, causing Consulate Dreadnought to become an artifact creature until end of turn.
Activate Phyrexian Altar by sacrificing Consulate Dreadnought.
When Consulate Dreadnought dies, Salvaging Station triggers, untapping Salvaging Station.
Repeat.
This clever loop transforms Salvaging Station into an infinite mana and sacrifice engine by continuously cycling Consulate Dreadnought back from the graveyard. While Phyrexian Altar provides the sacrifice outlet to fuel the loop and generate colored mana, Kolodin, Triumph Caster quietly does the heavy lifting: its static ability ensures that whenever the Dreadnought is returned, it instantly enters as an artifact creature without ever needing to worry about its steep crew cost. Each time you sacrifice the Dreadnought to the Altar, its death triggers Salvaging Station to untap itself, priming the station to pull the vehicle right back out for another iteration.
