Rotom-Wash From Tier 1 to Tier 1.5
It feels weird saying this because Rotom-Wash has been the most consistently good pokemon for the longest time, but Rotom-Wash is
really not liking the current meta. The amount of hyper offense teams right now is insane and, although rather bulky, Rotom-Wash cannot effectively switch in on any hits from popular HO mons (minus Talon). Similarly to Kyurem-Black, there are matchups where Rotom-Wash does wonders, and there are some where it just feels like dead-weight. If needing a water type for a team, I almost never consider washtom because Keldeo exists. Iunno I might be wrong here but I haven't seen Rotom-wash really pull its weight recently.
EDIT: Also getting buttfucked by literally every dragon sucks and I see either hydreigon, Kyub, or Latios on p much every team
