i've been using a fully physical set ever since i saw blightbringer destroy a smogon tour with it and i must say it's a really really really good set. i find it really funny that mixed sharpedo is walled by.......... blissey. yup, blissey. bold blissey takes 44% MAX from crunch (hpump does like 1% less), meaning it can actually switch into sharpedo's strongest attack, heal up and outstall its life orb recoil. in the rain barely anything can switch into fully physical sharpedo. imo it's a lot better at wallbreaking than the mixed set. blissey obviously loses to boosted waterfalls, but even max max skarm is 2hkoed by waterfall in the rain. other common physical walls (think gliscor) don't stand a chance either. i know this already passed qc and i sure as hell don't know where i was but yeah i can tell you this definitely deserves a set!
[SET]
name: Speed Boost (Physical)
move 1: Waterfall
move 2: Crunch
move 3: Ice Fang / Earthquake
move 4: Protect
ability: Speed Boost
item: Life Orb
nature: Adamant
evs: 252 Atk / 4 Def / 252 Spd
ice fang is cool because it lets you kill dragons, but earthquake can be helpful for the odd jirachi in the sand. LO + adamant nature + max attack is insanely strong, especially if you can keep rain up to boost those waterfalls. i like it a lot better than the mixed set because it's strong, gets the job done, and i hate relying on such a shitty move like hydro pump. good set, let's make it happen! i can write it up if you want... i do love my sharpedo
