>>43808444>non-legendary mythical pokemonThere's no confirmation that EVERY event-only pokemon is a mythical, rather (almost) every mythical is event-only. Kind of like how all squares are quadrilaterals, but not all quadrilaterals are squares.
Also being banned from the BF isn't justification of a pokemon's status as a mythical, the rotom forms are banned from the gen 4 BF the same way that spiky eared pichu is, and the hat pikachus are completely allowed in the battle tree.
