I've been trying to use it for a while, but I can't quite find its niche. it's bulky, but the slow speed and lack of recovery make it hard to keep around. even with max EV investment in SAtk it doesn't hit as hard as I expected, either.
lately I've been throwing it out on a resist and Mega'ing with a Cotton Guard. after that I either toxic whatever wall comes out or spam Discharge or Dragon Pulse until it dies. it does some damage and if I'm lucky takes out a poke while status'ing another, but overall, I just feel a little underwhelmed with him as a Mega.
I have to use him because he was my first caught shiny...
