This card is Aromaseraphy - Sweet Marjoram

It's really cheap, seriously. Like, around 10 yen 🤣 So I always thought this card was a common. Until today when I opened packs and was organizing my cards. I realized it's actually not a common. You can only tell under the light. This is a parallel rare (flat holo). I seriously thought it was a common for so long!! Can't tell it apart normally haha
