Looks like a cool set Hawkstar, sashed 'mons are less common this gen so there is a good possibility that you can get a surprise KO. Crunch is pretty much Tar's signiture move and is essential, Superpower is essential imo for Terrakion switch-ins and gets great coverage with Crunch, I'm not convinced that Stone Edge is necessary since a miss could cost you the match and I would personally go for one of Tar's wall breaking moves in Ice Beam or Fire Blast. Protect in the last slot is cool and supports the team but there will be comparisons made of whether scouting is more beneficial than setting Stealth Rock. A support move such as Stealth Rock or Pursuit might be better imo and SR works with Focus Sash to ensure success but I guess it depends what suits your team.
I am posting a new set that I have been playing around with lately. I am probably not the first one to think of this set but I have never seen anyone use these moves or in the context I am using them so I'll give it a shot.
It was originally designed to operate in my Sun team in the place of a Chlorophyll sweeper (yes I am mad) and I was sceptical that it would work at all but it has been eye-openingly successful so far. I think most of it is down to the surprise factor and it will probably not be very effective once everyone knows about it but I wanna post it and let everyone have fun with it (and maybe make it better *wink wink* ;D)! So here it is:
Raikou @ Life Orb
Trait: Pressure
EVs: 4 HP / 252 SAtk / 252 Spd
Rash Nature (+SAtk, -SDef)
- Weather Ball
- Thunderbolt
- Calm Mind
- Hidden Power [Grass]/Aura Sphere/Hidden Power [Ice]/Shadow Ball/[Your favourite coverage move of choice to complement Weather Ball]
Weather Ball is the bread and butter of this set. In Sun, it is a boosted 100BP Fire attack; in Rain, a boosted 100BP Water attack; in Sand and Hail, a Rock and Ice attack respectively. Weather is common this gen and luckily Weather Ball has fantastic coverage with Thunderbolt no matter what the weather.
You may have noticed that in Sun and Rain, Weather Ball hits even harder than STAB Thunderbolt on neutral targets which demonstrates the awesome power that's available. Calm Mind is for boosting Raikou's SpAtk to crazy levels and helps him get crucial OHKOs on neutral targets such as Gliscor that would otherwise threaten him.
I have geared this set towards use on a Sun team so I have selected HP [Grass] so you are not walled by Quagsire and friends but the coverage option depends entirely on what weather you expect Raikou to operate in. In Rain he has trouble with Celebi and Ferrothorn so Shadow Ball or Aura Sphere is appreciated while in Sand and Hail Aura Sphere is prefered for excellent coverage. Note however that Raikou does not get a boost to Weather Ball in Sand or Hail so he loses out on a lot of OHKOs which is disappointing.
Raikou's nature also has to be Rash because Weather Ball is an event move which means he loses out on the fantastic 115 Speed tier, another blow to his sweeping potential :( However he still outspeeds max Base 100 Speed Pokemon so it's still a respectable speed stat that has proved more than usable. Used early/mid-game Raikou can be a powerful lure, destroying many of his switch-ins with a high powered Weather Ball and he still hits crushes things with Thunderbolt. Late-game is when Raikou can seriously clean up and after one Calm Mind he can destroy even slightly weakened teams no matter the weather. Now that Chomp is gone a huge road block has been lifted and I think Raikou has a lot more potential in this new round of OU!
