I'm posting these movesets because I have never seen them before--and I think think that they are very usable and deserve some discussion.
Infernape @ Petaya Berry
252 Sp. Atk / 252 Spd / 6 HP
Timid Nature
- Nasty Plot
- Substitute
- Flamethrower
- Grass Knot
Explanation:
This infernape's purpose is to substitute right away. Then, if the opponent switches out, you can Nasty Plot on the next turn. After that, you continue to sub--while Nasty Plotting when possible--until you have little HP left. Even if you only get one NP in, you'll have a +4 boost on flamethower along with STAB (NP [+2) , Blaze [+1] , Petaya Berry [+1]) and a +3 Sp. Atk on grass knot (NP [+2] , Petaya Berry [+1]). Now, you'll be able to OHKO nearly all defensvive pokemon in OU--with some few exceptions that are 2HKOed. I've tested this infernape many times on shoddybattle, and it has sweeped teams 6-0--it's extremely powerful. It can come in at the beginning, middle, or end. Even if you can't pull off a nasty plot, petaya berry and blaze activation is still effective.
Damage Calculations against all defensive pokemon in OU:
Flamethower after 1 Nasty Plot, Blaze activation, and Petaya Berry activation:
Guaranteed OHKO:
Max HP, Max Def, Impish Forretress: 852.82% - 1003.11%
Max HP, Max Def, Impish Tangrowth: 428.22% - 503.96%
Max HP, Max Def, Impish Skamory: 400.90% - 471.56%
Max HP, 98 EV Sp. Def, Sassy Bronzong: 218.05% - 256.80%
Max HP, Max Def, Bold Weezing: 200.30% - 235.63%
Max HP, Max Def, Impish Donphan: 200.30% - 235.63%
Max HP, Max Def, Impish Gliscor: 179.10% - 210.45%
Max HP, 180 EV Sp. Def, Careful Dusknoir: 104.42% - 123.13%
Possible OHKO:
Max HP, Max Def, Bold Cresselia: 89.64% - 105.41%
Guaranteed 2HKO:
Max HP, Max Sp. Def, Careful Umbreon: 76.40% - 89.85%
Max HP, Max Def, Bold Blissey: 53.92% - 63.45%
Grassknot after 1 Nasty Plot and Petaya Berry activation:
Guaranteed OHKO:
Max HP, Max Def, Impish Swampert: 303.21% - 356.68%
Max Hp, Max Def, Impish Hippowdon: 174.76% - 205.71%
Max HP, Max Def, Bold Slowbro: 114.47% - 134.52
Max HP, Max Def, Bold Suicune: 102.72% - 121.03%
As you can see by the damage calculations, all the listed pokemon can be OHKOed or 2HKOed.
Counters:
The only counter I can think of right now is heatran, which will absorb flamethrower and take mediocre damage from grass knot. It might be good to pair this infernape up with a gyarados on a team.
Conclusion:
This infernape can really wreck a team if used properly. Substitute really makes a difference. Since infernape usually dies in one hit from most things, using a substitute will allow it to increase it's sp. atk with blaze and petaya berry before it dies. If you can fit in a nasty plot, it will only become stronger.
Swampert @ Leftovers
240 HP / 90 Def / 180 Sp. Def
Impish Nature
- Toxic
- Protect
- Counter
- Mirror Coat
Explanation:
This swampert has surprised many teams on shoddy battle. It's goal is to use protect first, scouting an opponents attack. Now, you can use either counter or mirror coat depending on your opponents attack. Toxic is put in the last slot because if provides good synergy with protect. You can also keep using protect every other turn to heal with leftovers while also damaging the opponent with toxic. It works surprisingly well. Eventually, swampert will be easier to handle once your opponent knows the moveset, but it can surprise an opponent well at first.
Damage Calucations:
None Needed.
Counters:
Any pokemon with a grass attack can probably OHKO this before it can pull off a counter/mirror coat.
Conclusion:
This swampert works surprisingly well, even though it will be harder to use once your opponent knows it's moveset.
P.S. To get counter and mirror coat on swampert, here is the breeding chain: Wobuffet-->Shellos-->Mudkip.
