Chocobos: Square Enix’s much improved horses. And no offense to horses (you know, in case their reading…), chocobos are way cuter, and cooler. Whether it makes sense to have them on playing cards or not, is totally irrelevant.
You want these cards for their swag factor, not their practicallity. Plus, it gives you an excuse to say “Chocobo” more frequently than you otherwise would. Let’s face it, it has to be one of the most enjoyable words to say. Thankfully, most people won’t know what you’re talking about anyway.
