I assumed that you've already got a Lucario, but I didn't evolve it just for dex-filling. Without evolving the Riolu it's useless if you want to pass its moves on.. For my Palkia? I guess that i'm looking for the typical great TMs, other event pokemons and IV passers.. I'll tell you privately how I want you to help me..
Hey man, how are you? I'm sorry for keeping you waiting, but now i'm glad to tell you that your ordered Riolu has finally evolved into Lucario [I wanted to thank you prorpely for your helping me]. Its level is 2, it has a neutral nature with the Steadfast ability, and a current EV gain of 1 Speed point. Tell me when you'd like to receive it. Actually I wonder whether you'll agree to help me some more in my new SS game. PM me please "^^
P.S: I've just received a shiny Palkia, Hasty nature, level 1 from the Ruins of Alph secret floor that i'd like to trade for some other cool stuff if you're interested..
