Swift swim on the other side is pretty useless on Mantine, since you don't really need to worry about outspeeding anything. Swift swim is for low speed sweepers who need to take advantage from rain. Mantine doesn't have neither the movepool nor the stats to be a sweeper, so Swift swim is essentially useless on it
True, very true, the Mantine I'm trying to create is everything on the defensive corner even bred in Haze so it could null stat changers. I took those kind of ideas in mind, but what I didn't think about (or forgotten as I've been breeding endlessly to the point where both skills looked pretty pointless) was Toxic. Swift Swim sounded cooler esp. on a Mantine which is why I leaned toward it more.
Okay, then, even if I think both skills are useless Water Absorb it is.
EDIT: Thanks for the advice.
