What kind of setup are you going to run?
So far all i've managed to read about is people running wild with mega kanga, xerneas, mega mewtwo and yvetal.
Ugh, I haven't really bothered with the ubers yet, will get owned.
@lupinko, 1st set would be great for a mew with heavy investment in defense thanks to WoW taunt + roost, usually a contact sweeper will not be able to kill you and will die of residual, also psyshock is better than psychic.
As for the baton passer, it looks good but if hypnosis fails and you get taunted you are going to be forced to switch out without passing boosts. I run hypnosis myself but it really is a lottery with that shady accuracy.
