I haven't ladder much lately, so I have to ask: are there people who even try to modify Denisss's formula? It is true that he uses Vaporeon, but if no one has really tried to modify his team, then it's not a staple of 3BP teams, it's a staple of Denisss's team, and I don't think we should rank a Mon just because it is used on 1 team that no one has attempted to modify for their own use. So long as you have outs for Quagsire and Clefable and at least 1 out for set-up sweepers, I don't see why you couldn't just pass beastly boosts to wallbreakers like Kyurem-B or Landorus-I. If people have tried to modify the team and the teams all proved inferior to Denisss's team, then I could understand giving Vaporeon a D rank since we did give it to Mr. Mime for that reason, but I would imagine it takes more than a week for such diversity to show up, if it exists. Also, from what I can tell from the post-nerf BP forum, it seems that most people just copy Denisss's formula, and those who are capable of innovating the team don't use it either due to it being too formulaic for them or due to its stigma.
