It's crazy how something that was niche last gen like terrain can move a mon like Hawlucha into the spotlight. Kingdra was a bit shocking to me, but I guess it shouldn't have been since it's the second best Swift Swim mon after Swampert. Ninetales-A will now be really good, as it totally destroys every relevant rain mon, sets hail/AV and can beat some more uncommon answers to the HO teams it sets up for like Quagsire.
I love OU right now because it is gravitating away from the concentrated, vile stall that was popular in the very beginning (Dugtrio + Chansey + Clefable + Toxapex + Skarmory + filler mon). UU on the other hand...
No surprise to see Tsareena and Decidueye drop. Tsareena is great for role compression, which makes me think it will remain a niche choice on UU teams, but the speed hurts it too much and it can rarely use its great Attack stat. Nidoqueen and Jirachi are surprising to me.
