Soul Car Counter

A Soul Car Counter is a used by "Soul Express Engine" monsters, represented as ghostly train cars that trail behind the monsters. Soul Car Counters are always initially placed on monsters by banishing monsters from either player's Graveyard, which is shown as the monsters being turned into blue flame-like souls before the car itself forms around them, trapping them within.

Soul Car Counters have two main uses. The first is to amass many Soul Car Counters on Main Deck "Soul Express Engine" monsters to increase their Levels, allowing them to use their effects to Synchro Summon their Extra Deck monsters using only one monster (as all Main Deck "Soul Express Engine" monsters are Tuner monsters). After performing these Synchro Summons, the Synchro Monsters gain every Soul Car Counter the Tuner had, allowing them to then use these Counters for their effects, either for constant effects or as ammunition.
