>>54522087As much as I want to say no, it can be useful if your team primarily struggles with Metagross. Having something like Togekiss or Florges in the front makes Vaporeon a great swap if your opponent either starts with or swaps into Metagross. There are definitely better water-types out there (Swampert, Gyarados, Golisopod, legendaries) and Excadrill fits that same role and does way more, but it is technically usable.
