OK, ok, lol. Meowth has something to say to youse:
What's the best nature for Gardevoir? Lonely or what? Considering he got Uber special stats already and it doens't need boosting, and he can't take a Shadow Ball anyways so I don't think Bold's gonna help much...LOL.
So i reckon Lonely is a good nature and max out Atk to at least 245+ and raise Sp.A and SP.D both to 300+. This set worked for me so far: Calm Mind, Shadow Ball, Psychic, HdnPower (Fighting, against Dark types, pwnz Tyranitar bad with 2HKO.), and for item i give him Lum Berry to exploit his Synchronize, LOL! But the only annoying guy here is Metagross...
So, yeah... might be just a weird moveset but I dont usually use psychics as so many other types can learn TM29...
BTW, Lonely is the nature I chose for Alakazam: 200+ atk, 350+ Sp.a and 300+ speed. with Substitute, Focus Punch, Psychic, Recover, again, pwned by Metagross ><...
