This is not a groundbreaking show. In fact it isn't even a show. When I saw the first episode I thought it was just mindless anime I'll play in the background which it is in some way. Just 3 minutes of moe. Nothing much to say. I only knew it was an add by reading comments if not I would have seen it as another slice of life aimed at kids which i'm fond of when I try to relax. So cute characters, generally with a character archetype personality doing silly things. In that case playing a card game. I think it's fun and it's nottrying to take itself too seriously or make some grandiose statement.

Watch it or leave it. Either way it won't change anything to your life.
