Hey guys, I'm back after digging this new thread up and seeing Sharpedo, which happens to be my favorite Pokemon. Here's my set.
Fast and Furious (All-Out Attacker/Wallbreaker)
Sharpedo @ Sharpedoite/Life Orb
Ability: Speed Boost
Nature: Naughty (+Atk, -SpD)
EVs: 232 Atk / 60 SpA / 216 Spe
- Crunch
- Hydro Pump
- Ice Beam
- Zen Headbutt/Taunt
I know what you're thinking, "There's a move that's obviously missing. No Protect? WHY?!" This Sharpedo excels much better early- to mid-game than late-game. The goal of this set is to handle defensive teams much better than its other sets, while also not being dead weight against offensive teams, thanks to its expansive coverage by forgoing Protect. Crunch is very difficult to stomach, at worst 2HKO'ing all neutral targets in the entire tier, barring only the bulkiest of physical walls. However, Hydro Pump and Ice Beam exist on this set to eliminate those targets, including Donphan, Forretress, Chesnaught, and Gligar. Their power isn't to be underestimated, as Hydro Pump even cleanly 2HKOs Cobalion with this spread. The last slot depends on whether you want Sharpedo to handle either more offensive or defensive threats. Zen Headbutt is usually the better move because it boasts a 75% chance to OHKO Heracross after Stealth Rock, OHKOs Toxicroak and Mienshao on the switch, and 2HKOs Virizion and AV Machamp, otherwise two of the best checks to this set. On the other hand, Taunt cripples walls on the switch that Sharpedo can't hurt much otherwise, such as Umbreon and Florges (although you will have to switch out). Just as a note, Earthquake isn't listed because it doesn't really accomplish much, since a neutral Crunch hits almost as hard on all Steel-types; Empoleon is 2HKO'ed by both moves and M-Aggron tanks both pretty easily.
Sharpedoite is the item of choice, so that Sharpedo is noticeably bulkier and can take some neutral hits, allowing it to fare better against defensive teams. Life Orb is an option to hit a bit harder on the special side and to better utilize Speed Boost against offensive teams, at the cost of recoil and longevity. An important note to remember is that most players expect Protect, which can be exploited against more offensive teams by attacking on forced switches, getting the Speed Boost, then Mega Evolving the next turn.
The Speed EVs let Mega Sharpedo outspeed max Speed neutral base 100's without a boost and max Speed neutral base 90's before Mega Evolving. The Special Attack EVs guarantee the 2HKO on Chesnaught with Ice Beam after Stealth Rock and Leftovers recovery, with the rest dumped into Attack with a positive nature to ensure the most powerful Crunch possible. Alternatively, the standard Life Orb spread can be used if running Life Orb.
Thanks for your time!
