Note that I don't have access to the game yet, so I can't show you what they do. All I can show you is the extreme joy of getting seven sealed character toys and not getting a single dupe. That's magical.
As far as I know, these are only available at GameStop, and my local GameStop only got one box, so good luck. Each cost $3.99. Using the power of math, that means I spent more than I probably should have on things I could not see.
Oh, and I did skip a guy in the video. It was normal forme Deoxys. No one cares about Deoxys.
