Playing through Y, could do with some help for my team. I've got the first three, currently looking for a Bergmite and then I'll most likely go back for a Skrelp, unless you have some better suggestions. I could really do with some combination of
Fire/Fairy/Dark/Steel/Psychic, and Golurk is my Flyer right now.

Chesnaught
Power Up Punch
Spiky Shield
Seed Bomb
Leech Seed/Hammer Arm

Golurk
EQ
Hammer Arm/PuPunch
Shadow Punch
Fly

Barbaracle
Shell Smash
Razor Shell
Night Slash/???
False Swipe (will replace with rock move)

Avalugg
Avalanche
Gyro Ball
Curse
Recover

Dragalge

???

So yeah, any tips for a final fifth/sixth member? Was considering using the Metagross I'd been using again, but wanted to see if there was something different/better.
