*lol*
I still have that notebook, where I recorded my trades and/or trade plans.
It says something like:
June 15, my 2:00 pm.
My Latias & Gardevoir for your Darkrai.
Although I just wrote there "Darkrai"...so I don't know if it's the one in the cherish ball (with both Dialga and Palkia's signature moves).
That was the time where I haven't learned the RNG process yet.
I just learned it last year.
