How will you counter Dragon Dancers, though? There're no steel types (aside from Magneton). There are no Pranksters so no priority Will-o-wisp. There's no Choice Scarf so no chance of outspeeding and a minimal of priority moves. Ice Shard's on 2 Gen I Pokémon (Cloyster being the best), Mach Punch and Bullet Punch on Hitmonchan.Actually I don't think that Moonlight + Unaware will be a good option, since this is 6VS6 there will be a lot of stall, and everyone and their mother will be prepared against Clefable (whether it is Toxic, cheesy techs, etc) so chances are that you will either lose all your Moonlight PP or be unable to setup due to Toxic after they figure out you have Unaware; so yeah, I think that Magic Guard + Softboiled Clef will be much better in this format, and you should definitely get it Skymin_Flower.
Dragonite scares me more than Clefable getting stalled.
body slam mega kangashkan .
Thomaz : while sludge wave is cool on weezing , sludge bomb is better. Weezing is a wall so the 30% chance poison is better than 10% more power . Unless you're the type of person would run a modest LO weezing :P .
No items. So no megas and no Life Orb.
