GEN VI: Looking for some pokemon to complete the mega stones I own

[dandelionfluff]

Hello! So I have pokemon x and I wanted to get complete the mega stones I have with their pokemon. I'm currently looking for Larvitar.
If anyone can get one I would love to trade you something that I can get in my game. I don't have many lengenaries or shiny pokemon so yeah
:ksmile:

I have some extra Larvitar lying around I can give you. I don't need anything fancy in return but I may need trade evolving assistance in the near future. If you have Omega Ruby I'd also like to borrow a Latios and a Groudon for pokedex entries.
