XD, to be honest, I already have a bold Milotic, just not with two egg moves, but that can be stomached. I'm a collector of sorts...and well, since you've put that as your trophy...I want it really bad, XD XD. Kinda like the grass is always greener? Ahaha, yeah...I'm horrible like that I suppose :(
In any case, if you really want to know my lead ,it's not a huge secret. I was just joking around :P It's a very common lead, in UU teams, XD.
Shiny (MUST be shiny to go with the whole rain dance theme - as is Ludicolo if you're using that) Electrode! Rain dance set up and then blow up in their face! All you need then is Taunt to prevent other mons from setting up. It's dangerous to use though...since if you run up against something scarfed...you might be in trouble...ie getting tricked would suck!
A safer option is Crobat - better stats and a tad bulkier ;P
