I'm sure I'm really late to the party, but I bought Y last week and beat it tonight.

Then I found out that I can't get the mega stone for my Tyranitar (My favorite pokemon) and instead I'm stuck with Agronite. Needless to say I am agitated.

So is there anyone still out there who'd be willing to accept a random Pupitar of mine with Agronite in exchange for a Lairon with Tyranitarite?

What a shitty pick on exclusive stone. How many people would rather have a Mega Agron tan a Tyranitar? Not many.
