I would highly suggest getting a pretty good moveset for mew, (you can gave it something like nasty plot+3 attacks? Don’t know about the item). Also, you have a large repeating type. Ordinarily, this would not be an issue, but both of those mons play a similar role and they have somewhat similar coverage. I would suggest replacing one of those psychic types with a fire type. Fire types or fire type moves tend to be pretty solid in the e4 as they love to have a certain mon (scizor).
