When the teacher is lecturing you, and you're so bored you could almost fall asleep, what else to do besides make a team?
Introduction
I really wanted this team to succeed in the normal ladder. Since we may not have Garchomp much longer, I had to replace him with another physical sweeper. I wanted to test that and the rest of my team out. I had had many problems against Salamence (especially BulkyMence) in the past, so I wanted to revolve around countering that. This is the result of that team. (And the lecture).
Gengar @ Focus Sash
Nature: Timid
Ability: Levitate
EV Spread: 252 Special Attack/252 Speed/6 HP
Moves:
Shadow Ball
Focus Blast
Thunderbolt
Hidden Power [Ice]
This Gengar has swept many, many teams. With its amazing type coverage, it hits everything in the game for neutral with only 2 moves. The other two moves are pretty much filler. Hidden Power Ice takes care of my Bulkymence problem, easily OHKO'ing any Bulky or DD set. Thunderbolt hits Gyarados hard.
Infernape @ Life Orb
Nature: Naive
Ability: Blaze
EV Spread: 252 Special Attack/232 Speed/24 Attack
Moves:
Flamethrower
Close Combat
ThunderPunch
Hidden Power [Ice]
This is a pretty standard Mixape. Thunderpunch over Grass Knot simply because I already have Swampert coverage on this team. Flamethrower deals plenty of damage with STAB, especially when Blaze is activated. Close Combat OHKO's Max HP/Def Blissey, and Hidden Power Ice takes care of Garchomp/Salamence/Flygon/Dragonite.
Dugtrio @ Choice Band
Nature: Jolly
Ability: Arena Trap
EV Spread: 252 Attack/252 Speed/6 HP
Moves:
Sucker Punch
Earthquake
Aerial Ace
Stone Edge
Dugtrio is replacing Weavile for the moment. This has the ability to trap and KO things like LOtran and Yachechomp. Aerial Ace can OHKO Heracross, Rock Slice can kill most fliers (and possibly get a flinch too!), Earthquake deals loads of damage with STAB, and Sucker Punch is for the Choice users.
Jirachi @ Leftovers
Nature: Modest
Ability: Serene Grace
EV Spread: 252 Special Attack/252 Speed/6 HP
Moves:
Psychic
Thunderbolt
Grass Knot
Hidden Power [Ice]
This is a recent addition to my team. Jirachi can take hits very well, and can deliver them too. The only way this Jirachi has ever died is because of crit hax. Psychic can hit opposing Gengars hard, and pretty much anything else. Thunderbolt can OHKO Gyarados, Grass Knot OHKO's Swampert, and Hidden Power Ice hits Dragons and Fliers.
Blissey @ Leftovers
Nature: Bold
Ability: Natural Cure
EV Spread: 252 HP/252 Defense/6 Special Attack
Moves:
Seismic Toss
Softboiled
Thunder Wave
Ice Beam
This is a pretty standard Blissey. Thunder Wave was chosen over Aromatherapy because of the necessity to cripple things like Gengar. Seismic Toss can help me wear down my opponents, Softboiled is obvious recovery, and Ice Beam is simply for the fact that I don't get walled by Ghosts.
Salamence @ Leftovers
Nature: Jolly
Ability: Intimidate
EV Spread: 252 HP/176 Defense/82 Speed
Moves:
Dragon Dance
Dragon Claw
Earthquake
Roost
Credit to Aldaron for this amazing set. This has ripped through many teams while walling them in the process. I Dragon Dance while taking minimum damage from puny things like a Lucario Extremespeed, I roost off the damage, then proceed to sweep. Dragon Claw + Earthquake is only resisted by Skarmory and Bronzong, which can help. A lot.
Well, there you have it. Thanks for reading. Please help!
