Looking for celesteela and pheromosa

Hey guess I'm looking for a celesteela and/or a pheromosa. I'm looking to complete my Pokédex. I don't even want to keep them o just want to register them so I'd be willing to just trade them right back. Which I know probably seems a little skeptical so it you want I could also trade to a Pokémon of some kind of value to make sure I trade yours back. So if you would really like to help me out it would be really appreciated. Thank you :)

Hi, try looking in the Trade Corner. There are lots of people who offer exactly this kind of service for free :)
