I'm having a lot of trouble with Yanmega, Heracross, Gengar & Weavile.

Please don't tell me to change the luck based items, they do wonders : D

Any tips on the moveset or should I change any Pokémon?

PS:: Yes, I'm aware most of my team is weak against ghost, bug & dark :/

Eh, could work as a lead I guess. I know you don't want to change ur luck based items, but a Focus Sash on this thing can really help, along with Shadow Sneak over Psycho Cut, unless you are skeered of dem Machamp Lead. WoW also seems out of place too. Maybe Taunt?

Eh, alot of leads will set up SR on you, so I wouldn't use Focus.....wut. Band? 1/10 is not great lol. Change T-Bolt to Crunch to hit Latias, and Gengar, and Cressie (unless they WoW you first lol. Lum berry?)

Fine. Personally, I like the BP set better but what ever. Change the Psychic on either Espeon or Gardevoir to Flamethrow or **** like that.

Another Psychic? No wonder you have a ghost/Dark/Bug weakness xD. This set is still workable though lol.

Scizor currently ***** ur entire team. This team is really off balence imo, and I highly recomend you change your team so it has a higher type diversity. A Scizor aboslutly destroys the Yanmega, Hera, gengar and Weavile btw.
