Hey I've got a team that I've been play testing a bit and I feel that it's good but might have some gaps that need fixing. The basic idea of the team is Parafusion-Flinch with Jirachi Machamp combo. In play testing I've had ok results but I think there are some wholes that can be filled.
My Team: Machamp, Jirachi, Gyarados, Mamoswine, Jolteon, Gengar
Machamp
Item/Lum Berry
Ability/No Guard
Nature/Adamant
EV Spread: 4 HP/252 Atk/252 Spd
Moveset:
Dynamic Punch
Bullet Punch
Payback
Stone Edge
Machamp's job is pretty simple, hit with Dynamic punch and get the confusion so I can switch into Jirachi. However I usually find that if I can two hit KO something or get the KO with priority Bullet Punch then I'll just stay in and get the KO. I can also out predict my oponent and hit Ghosts on the entrance when they switch to take Dynamic Punch. I haven't found that I use Payaback much though, but I can't figure out what to get to replace it. I want to because Payback is useless since if I'm outsped then I'm probably KO'd. Suggestions?
Jirachi
Item/Leftovers
Ability/Serene Grace
Nature/Adamant
EV Spread: 216 Atk/32 Def/252 Speed
Moveset:
Iron Head
Ice Punch
U-turn
Thunder Wave
Jirachi's job is also pretty simple, get the T-Wave off after the switch in from Machamp and then start Iron Heading for the flinch, para or confusion hax. I can also U-turn out back to Machamp if a new poke comes out or just stay in and T-Wave. Ice Punch is nice for Dragons and Grounds. Really I don't know that I would change anything with Jirachi but I'll take suggestions.
Gyarados
Item/Lum Berry
Ability/Intimidate
Nature/Naive
EV Spread: 4 HP/252 Atk/252 Spd
Moveset:
Ice Fang
Bounce
Waterfall
Dragon Dance
Gyarados is really just a sweeper, I can bring him in if the Machamp Jirachi combo fails and typically do well. Waterfall is a good STAB while Ice Fange can hit pretty hard against Dragons and Flyers. Dragon Dance for nice setup, but I'm finding Bounce to be pretty useless. It misses a lot and I can never hit a super effective hit, I'm thinking of switching it with Earthquake to hit Electrics. I know this moveset with Earthquake works well because I used it when I played through my Diamond game. Suggestions?
Mamoswine
Item/Life Orb
Ability/Thick Fat
Nature/Adamant
EV Spread: 228 Atk/28 Def/252 Spd
Moveset:
Ice Shard
Icicle Crash
Earthquake
Stone Edge
Mamoswine is another physical sweeper and I really like this set. Icicle Crash and Earthquake are good STABs while Ice Shard is a really nice priority to finish off weak pokemon. Stone edge for some nice coverage. I find that this set can really work and can sweep through most teams nicely and weaken them down. Suggestions?
Jolteon
Item/Focus Sash
Ability/Volt Absorb
Nature/Modest
EV Spread: 4 Def/252 SpAtk/252 Spd
Moveset:
Volt Switch
Thunderbolt
Agility
Shadow Ball
Jolteon is one of my special sweepers and I find he can work well by getting the kill with sash. T-bolt for a good stab and I can Agility when I predict a switch. Volt Switch to help scout and shadow ball for some coverage. I find that this set can sometimes work but obviouisly is walled by Grounds. I don't know if Agility really works because it doesn't boost special attack. I can also switch in to him when I predict an Electric attack and take it with Volt Absorb. Suggestions?
Gengar
Item/Focus Sash
Ability/Levitate
Nature/Timid
EV Spread: 252 SpAtk/4 SpDef/252 Spd
Moveset:
Sludge Bomb
Shadow Ball
Pain Split
Hidden Powe (Fire)
Gengar is my final special sweeper and I like this set pretty well. Sludge Bomb and Shadow Ball for awesome STABs, Pain Split for some regeneration because I can outspeed a lot of things, and HP Fire for some coverage along with being able to switch in and surprise things like Genesect and Scizor. I also find that I can switch in if I predict an Earthquake on Jirachi or Jolteon. I can also switch if I predict a Fighting move on anyone. Overall I like this set on Gengar a lot. Suggestions?
As you can see this is more of a hybrid stall/offensive team. To be fair though I got most of the team from someone that I played against who used it and I found it to be pretty good against me. I have a lot of options but also this team relies heavily on predicting your opponent and I have to say that I struggle with this sometimes, staying in with Machamp on a faster Flying type trying to go for the Stone Edge, or a Psychic. Or I make stupid switch ins, overall though, I think this team works fairly well and I just think that there are a few kinks that need to be taken care of. I'll be happy to take any suggestions as long as they are productive.
