Just my quick opinions ;
Mega Sceptile: broken as anything, ban asap wayyy too fast and powerful, too much for NU at this time.
Mega Beedrill, this is interesting, I do feel that mega beedrill is kinda bad in this tier when so much stuff checks it, it can uturn out yes, but it'll be doing 0 damage to say: a steelix and rocks can't stay off the field forever. We can keep this for r2 if people really want to give it a chance
Slurpuff: shouldn't really be banned, its an nu poke and surely it can't be too duffivult to keep calm. You have offensive checks in pyroar and defensive ones in bulky poison types. More threatening yes, but not quick-bannable imo
