So after playing a lot of matches on Shoddy, I have found that:
-CM Cress is a *****, especially with Rest and Sleep Talk or Psycho Shift. However, it isn't impossible to beat, since if it runs CM, Rest, and Sleep Talk, the last move is easy to wall. Psycho Shift is harder and requires me to have a PHazer and such. Both fall to PHazers.
-Cress is overall a great Pokemon in UU. I don't think it is broken though. It seems like a great supporter and can hit decently as well, while being able sponge attacks. It can't hit hard enough without CM or Charge Beam from my experience though.
-There has been an increase of Sun teams, and from my experience, they aren't doing too well, though it might be the fact that the people on Shoddy right now don't seem as good. Maybe they will be better when people get more experience with Cress?
-Pory-Z tears rips huge holes in teams. It sweeps slower teams with ease and doesn't fear much, especially when it is bulkier than Yanmega, who Pory feels like.
-Pory-Z, I feel is as broken, if not more broken that Yanmega. Yanmega had to fear SR as well as priority and wasn't nearly as bulky. Pory only has to fear priority and can easily shave off any damage done to it with Recover.
-Also, I have noticed much more sand teams than usual.
