While I know Timid/Modest IV 31 all frames are easy to hit (since I've done them a LOT), I don't know off the top of my head Timid 5 IV frames. So if the Atk IV being 31 doesn't really matter to you, then... no problem.
Any of the special attack Legendaries... Would that include Groudon, since Primal Groudon can work very well with Sp. Atk? I guess technically, almost EVERY Legendary can be made Timid for something to happen. And I don't remember if I gave you any Legendaries before, so... I'll list all the Moon Ball-able Legendaries from HGSS and you just pick which ones you want.
Articuno, Zapdos, Moltres, Mewtwo, Raikou, Entei, Suicune, Lugia, Ho-oh, Latias/Latios, Kyogre/Groudon, Rayquaza
And for each Legendary, I guess I'll find one Pokemon I need in SM for them. And for the sake of trade fairness, if you could just attach one Rare Candy on each one, that'd be great.
Also... what is with Moon Balls, anyways? I don't recall trying to catch Legendaries in... say... Lure Ball. Or Love Ball. Always the Moon Ball. Huh.
