>>30418266Wishiwashi is gimmicky, never tried it, but I'm pretty sure it works just fine in-game, specially early game.
Araquanid is a monster. You probably don't know the hidden effect of its ability (doubling power of Water-type moves). I 2HKOd Totem Wishiwashi with Scald with a Dewpider, which is a 1st stage mon, coming from its weaker offense stat.
Golisopod is also a monster, you probably just didn't realize you're supposed to run it full priority. Breed Aqua Jet to it (not too hard, just get a female Wimpod and a male Tirtouga) and have fun. I just did it, and I'm pretty sure it'll kick ass.
There's also Toxapex. Mine is still a Mareanie, which is much weaker than the evolution, but still managed to defeat both the Fire and Grass Totems by itself, and holds its weight very well.
