Legendary Pokémon

I have Pokemon that I will trade for these Pokemon that I am seeking out, so just let me know what you would be willing to trade for and I will see what I can do? ^^

Searching For;

Darkrai
Celebi
Mew

... I think those are the only ones I really am gunning for.
Missed the darn events so I thought Id give this a shot. ^^

Thanks for your time!
