I've been testing another generic bulky powerful Rock type, and its actually had good success.
Rhyperior @ Weakness Policy
Ability: Solid Rock
EVs: 252 Spd / 252 Atk / 4 HP
Jolly Nature
- Rock Polish
- Earthquake
- Rock Slide
- Ice Punch
One of the best Weakness Policy abusers, this set is similar to Electricstorm252's Weakness Policy abusing set. Rhyperior just has insane physical bulk, taking even many super effective hits with ease. Seriously, just look at these calcs:
252 Atk Choice Band Hustle Durant Iron Head vs. 4 HP / 0 Def Solid Rock Rhyperior: 310-366 (83.3 - 98.3%) -- guaranteed 2HKO
252 Atk Cobalion Close Combat vs. 4 HP / 0 Def Solid Rock Rhyperior: 184-217 (49.4 - 58.3%) -- 98.8% chance to 2HKO
Two very powerful physical attackers that have STAB SE moves, not even OHKOing. I know there are alot more examples, but I wouldn't want to flood this post with calcs.
Anyways, when luring in a SE attack (hopefully Physical, though Rhyp's hearty HP lets it take special hits), it can Rock Polish easily, getting a Shell Smash without the Defense lowering. And trust me, you do NOT want to face a monster with 758 Attack and 392 Speed with EdgeQuake STAB. It's just so easy to use, and its very unexpected.
Earthquake is just an amazing STAB, destroying everyone in its path. I prefer Rock Slide over Stone Ege bc bs misses, though seriously, the only reason you use Rock Slide over EQ is to hit resists (Bug and Flying get Wrecked) and Levitators (Azelf and others get wrecked as well), making Rock Slide the better option. Ice Punch hits pokemon that just happen to resist EdgeQuake (See: Virizion), but most notably, Gligar. STAB on EdgeQuake just is so effective, along with the coverage in Ice Punch.
However, even though one of Rhyp's best checks, Slowbro, is hidden away in UU, two huge checks to Rhyp are still in the game, Bronzong and Gligar. Bronzong gets hit by Fire Punch, but it requires getting rid of Ice Punch, which hits Gligar. There are other walls, such as Alomomola, that Rhyp which it had another coverage move, but it can't afford to give up. Basically, it has pretty bad 4MSS.
Even with its few flaws, Rhyperior still destroys everything while taking a SE hit, which makes it a pretty good sweeper/tank should your team need one :)
