LF Charizardite/Mewtonite X, Manecrticite, Pinsirite FT Charizardite/Mewtonite Y, Houndoomite, Heracronite

I'm just looking to get the X exclusive mega stones, let me know if you'd be willing to trade some for the Y exclusive alternate (Heracross-Pinsir, Houndoom-Manectric, etc.).

Thank you!

EDIT: I also need the Tyranitar mega stone, but I don't have a spare Aggron one to trade for it. If you have one, I can try and get you something else.
