I have this Swampert:
Adamant
31/31/30/31/31/30
Hidden Power: Psychic 70
So far he has Earthquake and Waterfall
What can I put in the last two slots?
Swampert @ Leftovers
Ability: Torrent
EVs: 252 HP / 4 Atk / 252 Def
Relaxed Nature (+ Def / - Speed)
- Earthquake
- Ice Beam
- Stealth Rock
- Roar / Surf / Yawn / Protect
Using Ice Beam instead of Waterfall gives you nearly perfect coverage in OU, while also damaging threats like Celebi, Latias, etc. Last slot is a toss up, Roar for phazing, Surf for Rotom-A and Skarmory, Yawn for pseudo-phazing, and Protect for scouting Choice item holders.
Or:
Swampert @ Choice Band
Ability: Torrent
EVs: 136 HP / 204 Atk / 68 Def / 100 Speed
Adamant Nature (+ Atk / - SpA)
- Waterfall
- Earthquake
- Stone Edge
- Ice Punch
EVs allow you to never be 2HKO'd by Choice Band Tyranitar's Stone Edge, whilst Timid / Naive Heatran can't 2HKO Swampert with Fire Blast. 100 Speed EVs let you outspeed most Skarmory, Tyranitar, and Metagross.
I need to know if I have the correct natures for these Pokemon:
Regirock: Quirky, Impish
Registeel: Naughty, Relaxed
Regice: Bold, Relaxed
Cresselia: Mild
Jirachi: Lonely
Regirock: Impish is decent, you want to aim for Careful though. And, Quirky is a bad Nature for anything.
Registeel: Registeel's Attack is horrible, so Naughty is generally bad for it. Relaxed is alright.
Regice: Regice wants a Special Defense boosting Nature, but Bold and Relaxed is passable.
Cresselia: Lowering Cresselia's Defense makes it more susceptible to Pursuit users, and gives it a harder time switching in, so no.
Jirachi: Decent I suppose for physical variants.
