Scroll down to D rank where you will see Mega Beedrill and click on the "reasoning" button. It explains why you shouldn't use Mega Beedrill in NatDex UU. On that RMT answer, I'd replace Beedrill with something else since Mega Beedrill requires exceptional hazard control since it is a rocks weak Pokemon that uses U-turn 90% of the time. And in the Pokepaste and your team in general, you don't have a way to remove hazards from your side of the field.
Sorry for the rant, but I just wanted to educate you on why you shouldn't use Mega Beedrill in NatDex UU. That Pokemon is honestly a noob trap Pokemon in the tier.
