Obviously it's going to get raped by anything with a water/grass type move, I wasn't saying it won't but Hippo with evo stone does all of Hippo's regular jobs better. Just saying.Go, Mantyke/Chinchou/Horsea/Lotad/Buizel/Clamperl/Feebas! Use Agility/Shell Break/Rain Dance/Splash! Now use Surf/Hydro Pump/HP Water!
It's a OHKO!
@ above: if a pokemon with Quick Attack can't switch in, it can't counter, only revenge. Like with Salamence and Ice Shard, that doesn't work.
Also, 65/45/45 defenses are fairly good, around Machop-level. Machop takes less than 50% from most Quick Attacks.
