Honchkrow would be awesome to use in RU. Unfortunately, I don't think it'd stay for long. It has great coverage, and with its Moxie ability it's very hard to stop once it gets the ball rolling. I guess it's sort of like Yanmega in a way.
Shame that NU didn't get Trevenant. Either way, I'm excited for what we did get regardless.
Mawile seems interesting. PU getting another Fairy-type would be neat. It can go offensive or defensive, though it's fairly obvious to tell the difference between the sets because defensive sets will ALWAYS run Intimidate and offensive sets will ALWAYS run Sheer Force.
RIP Zapdos. But hey, we got....Conkeldurr, Celebi, and Sylveon I guess. However, I'm kind of scared because Conk dropping means we're eventually going to see Machamp drop to RU. Chances are Machamp would get quickbanned from that tier, but still, it'd be annoying to face for the short time that it will likely be available.
I guess no more Amoonguss means SOMETHING got better in RU, right? Well, I think defensive Tangrowth is more viable now, but even then there's Venusaur....... Quagsire leaving is not a huge loss, but it does mean that Malamar gets one less check in the NU tier. Stall players man.
