Is shadow tag banned from Chandelure and if yes why?

Question

I heard people say that shadow tag is a great ability on Chandelure but apparently it doesn't exist on it, was it too op? Feel free to correct me if i'm wrong

Answer 1

Shadow Tag Chandelure has never been legitimately obtainable; it was Chandelure’s Hidden Ability in Gen 5 only, but it can only be obtained with its HA in Gen 6 through the Friend Safari, after it was changed to Infiltrator. Game Freak gave it Shadow Tag, but decided it would be too OP and retroactively changed it before it could ever be used in battle.
