If you’re talking about X, theres no midfakes of X. if you mean mfb, theres a couple factors. For mfb you can usually tell by box codes, and anything screwed up like the quality of the box art and saturation. On the bey itself, facebolt codes are a pretty well known one but not for sonokong as some real sonokong beys do NOT have facebolt codes as well as some zero g mids can have fb codes. Theres also the mold quality of the wheel and any noticeable defects. Thats just the tip of the iceberg lmao but yeah its tough out here.
