Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I hope it's not a problem for you, but im afraid we should postpone the trade till the 14th of July (I'm abroad right now and don't have access to my 3DS until then). Hope you're not in a rush and can trade when I'm back!
I just noticed that you wanted a Modest Celebi, i just checked my boxes and i only have a timid hp fire one and flawless bold/calm. Do you need any of these?
If you want to use Charmander for breeding, feel free - but please credit me.
I'm not about to trade for another few hours at least as I'm at work, but as soon as i'm available i'll let you know.
