Just gonna take a shot-in-the-dark guess here, but the black cars we've seen so far all have something to do with forced discarding. I'm willing to bet that there are some unreleased ARTS or SIGNI that gain some pretty fun benefits from having a discard pile of a certain size. Similar to the Black ARTS card that lets you destroy all active SIGNI when your Trash pile is 25 cards high
