Yeah, Armaldo is kind of the weak link on that team. I thought it would be a nice answer to rain teams with swift swim, but Toed still outspeeds it. Galvantula and Scizor are better answers to rain teams than Armaldo, in my experience.
I'd usually use it to set SR, but then I wouldn't be able to do anything else with it, even with the sash, I can't ever get enough speed to outspeed a lot of stuff for an offensive move.
Not changing this sig until The Undertaker vs. Chris Jericho happens on PPV (started October 4, 2009)
