Here's why:
* LE09 is not a set code in Yu-Gi-Oh! The set codes usually follow a pattern like "LCKC", "LODT", or "MRD".
* EN002 would suggest a common card in the English set, but the number is not in the typical range for common cards.
It's possible you are misremembering the card's name or set code, or the card may be a custom one made by a fan.
