Ninjask

Surprisingly, Ninjask performs better in Ubers than in OU, due to the preponderance of Psychic- and Dark-types and the lack of dedicated phazers in the former tier. However, using Ninjask does come with its share of problems: if the opponent sends in Groudon or Lugia, you'll definitely be starting the match off on the wrong foot, so your team should be able to handle them. But otherwise, you'll be surprised at how easy it is to pass to a sweeper and potentially run through an opponent. With some planning, carefulness, and a bit of luck, Ninjask can be a real asset to your support-oriented team.
