LETS GO Bulky Offence

Melmetal and Golbat hold off the whole physical metagame. Golbat also stops Venomoth from setting up. Melmetal provides an offensive check to Muk with T-Wave, immunity to poison and quake. Chansey gets rocks super reliably and can easily stall out physical attackers with reflect + toxic. Loses to Muk, obviously. Scyther does the actual winning, outspeeding most stuff and pretty freely getting to +6 against most defensive mons. X-Scissor can be replaced with Aerial Ace if you're scared of Venomoth, but its nice to be able to break Slowbro. Mew is also just really good at breaking stuff, although the speed is more of a problem. Just don't let chansey get toxiced, and try not to bring in Golbat if rocks are up unless its absolutely necessary.
