From the description of the video:

This guy on my friends list kept challenging me to a battle using the annoying sturdy paralyzed Shedinja gimmick, and I kept [messing] him up and he kept disconnecting on me every time I did, only to beg me to battle him again, asking me to "not kill them" until he had set up his trick. And even though I kept telling him "no I know the trick I'm not falling for it" he kept challenging me.

I kept battling him and messing up his set about 5+ times (and he'd disconnect as soon as I did) before I decided to let him set up completely and just attempt to stall him as long as I could to waste his time and hopefully make him realize that it wasn't worth it.

And then this happened.

HA HA HA.

Whisk Yourself Away Into the Faniverse!

In case she didn't realize, I was just trying to pass by. If she needs peace and quiet, why didn't she just leave me alone? I'm going to pwn your Pokemon anyway, then you won't be able to spend time with them. Lose-lose situation right there.

I should have know Deoxys wouldn't be in a Grass safari... But still...
