Please note that this team is not usable in RU, as Claydol, Krookodile, and Sharpedo are banned.
This questions is answered, but I'm still open to new ideas so if you have any, please drop 'em off in the comments or an answer.
Archeops @ Choice Scarf
Ability: Defeatist
EVs: 252 Atk / 4 SpA / 252 Spe
Naughty Nature
- U-turn
- Stone Edge
- Hidden Power [Ice]
- Earthquake
Scarfed U-turner with 110 base Speed is good. I get to switch to a Pokémon that can better counter the opposing one, if Archeops can't handle it.
Stone Edge is the choice of Rock-type STAB.
Hidden Power [Ice] for Gligar.
Earthquake has good coverage, 100 power, and decent accuracy—it's a little bit of filler.
Dusknoir @ Leftovers
Ability: Pressure
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Substitute
- Focus Punch
- Shadow Sneak
- Pain Split
Substitute blocks annoying status, and Focus Punch has 100% accuracy and 150 base power. It gives perfect, at least neutral, coverage against everything, along with a Ghost-type move.
Shadow Sneak is priority and STAB.
Dusknoir can finish off his foes if a Focus Punch isn't enough.
Pain Split works well with good defenses and low HP to heal from the sub damage.
Accelgor @ Life Orb
Ability: Sticky Hold
EVs: 4 Atk / 252 SpA / 252 Spe
Timid Nature
- Bug Buzz
- Focus Blast
- Giga Drain
- Hidden Power [Rock]
Bug Buzz is a strong STAB.
Focus Blast has a nice 120 BP if Bug Buzz isn't effective, and it provides further coverage.
Giga Drain heals Life Orb damage and hits Quagsire.
Hidden Power [Rock] is for Moltres.
Claydol @ Leftovers
Ability: Levitate
EVs: 252 HP / 128 Def / 128 SpD
Bold Nature
- Rapid Spin
- Stealth Rock
- Earth Power
- Toxic
Rapid Spin helps Archeops and the team overall by removing entry hazards.
Stealth Rock helps my team get KOes more easily.
Earth Power is an offensive option if Claydol needs to attack.
Toxic can wear down threats that might otherwise be difficult to handle.
Rotom @ Life Orb
Ability: Levitate
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Shadow Ball
- Thunderbolt
- Substitute
- Pain Split
Another Ghost-Sub-Splitter!
Shadow Ball and Thunderbolt hit much of the tier neutrally and some super effectively, and both are great STAB moves.
Substitute blocks status, and Rotom doesn’t faint from the opponent’s attack—very nice shield.
Pain Split heals Sub + Life Orb damage and helps recover general damage.
Krookodile @ Choice Scarf
Ability: Moxie
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Earthquake
- Crunch
- Stone Edge
- Pursuit
Earthquake is good coverage and STAB.
Crunch is another great STAB and hits Psychics super effectively.
Stone Edge, along with Earthquake, provides excellent coverage, mainly hitting Flying-types.
Pursuit traps and finishes off opponents with STAB.
Krookodile is now UU in Smogon.
Sharpedo @ Life Orb
Ability: Speed Boost
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Waterfall
- Crunch
- Aqua Jet
- Earthquake
Waterfall is an awesome STAB with a nice flinch chance to bait if necessary.
Crunch is the other STAB move, hitting Pokémon that resist Water-type attacks.
Aqua Jet is the Protect of the set, but instead of Protect, Aqua Jet is priority for the team. The Speed Boost is meant to be gained on a revenge kill with Aqua Jet.
Earthquake isn’t that useful, but it hits Electric-types harder and is the strongest move against opposing Sharks.
Please leave suggestions!
