I am offering a Darkrai (Japanese, met at level 50, Platinum, UT). I'll explain the details in a pm.
I am looking for a Shaymin (LEGIT only, preferably TRU). I don't care about natures or IVs or anything like that. This is really for collecting purposes/pokedex. My game is Pearl so I won't be able to get the flower item from Platinum. I also would accept a Dex trade (trade, then trade back so I get the data).
Pm if you want to go with this trade, and I know Darkrai is old news, but it's the only event pokemon I have.
EDIT: Trade completed. Thanks, son111goten.
