Hm... I'd like a shiny Mewtwo, Entei, Raikou, Suicune, Ho-Oh, Lugia, Bulbasaur, Charmander, Squirtle and maybe 3-4 Mews.
I also bold faced the Pokemon I wanted the most in case you weren't willing to trade all that xD
I am not sure what to offer though, so you can ask for anything, since I'd be willing to give you anything ^^
If you want an offer though I can give anything from this list Xerneas, Zygarde, Master Ball, Gardevoirite, Everstone, Absolite, Manecite, Blazikenite, Lucarionite, Venusaurite and I can search for other Mega Stones if you like
