Activate The Last Ride's crew ability by tapping a creature with power 2 or greater, causing it to become an artifact creature until end of turn.
The Last Ride dies as a state-based action due to having 0 or less toughness, triggering Salvaging Station and Open the Graves.
Resolve the Open the Graves trigger, creating a creature token.
Resolve the Salvaging Station trigger, untapping it.
Activate Salvaging Station by tapping it, returning The Last Ride from your graveyard to the battlefield.
Repeat.
This ingenious engine turns The Last Ride's massive self-inflicted toughness penalty into a perpetual motion machine, using its own death to immediately fuel its return. By crew-activating it into an artifact creature, you ensure that its life-total-based -X/-X state-based action sends it straight to the graveyard, which triggers Salvaging Station to pull it right back onto the battlefield. Meanwhile, Open the Graves watches your nontoken creatures perish and continuously populates your board with 2/2 black Zombie creature tokens to keep the loop going.
