I know I’m not quite finished with the Major Arcana, but I’ve hit a bit of a snag with the remaining cards, and figured I might as well start the minors while I’m at it. I figured I’d make the minor arcana with OCs, as assigning each of the 56 cards a background pony would have taken ages in research. As well as having a certain group of ponies fit the particular suit of minor cards.
