Quick Glance at Team:
__________________________________________________________________
Indepth Look:
Venomoth @ Black Sludge
Nature: Timid
Ability: Tinted Lens
EVs: 160 HP / 212 Speed / 96 Sp Atk / 42 Sp Def
Moves:
~Sleep Powder
~Toxic Spikes
~Roost
~Bug Buzz
~Venomoth is a much needed poison type on this team since Toxic Spikes are all over the metagame in UU. Sleep Powder to put a poke to sleep and buy an extra turn to use Toxic Spikes. Roost to regain back some HP and Bug Buzz for an awesome STAB move with Tinted Lens for more coverage.
Slowbro @ Leftovers
Nature: Bold
Ability: Own Tempo
EVs: 252 HP / 252 Def / 6 Sp Def
Moves:
~Slack Off
~Calm Mind
~Surf
~Ice Beam
~Slowbro is my Physical Wall. He takes Fire Moves well and is a complete wall to Blazikens who don't have Hidden Power Electric. Calm Mind to make it have good Sp Def and Sp Atk and possibly go for a sweep. I chose Ice Beam over Psychic because I feel it has more coverage in UU.
Magneton @ Leftovers
Nature: Modest
Ability: Magnet Pull
EVs: 160 HP / 252 Sp Atk / 96 Speed
Moves:
~Magnet Rise
~Discharge
~Signal Beam
~Hidden Power (Ground)
~I prefer this "bulkier" version of Magneton compared to the Speed and Sp Atk version for the lack of bulky pokes on this team. Magnet Rise for ground type attacks, Signal Beam for any Dark or Psychic type, and Discharge for STAB and parahax.
Mismagius @ Leftovers
Nature: Timid
Ability: Levitate
EVs: 252 Sp Atk / 252 Speed / 6 Sp Def
Moves:
~Substitute
~Shadow Ball
~Thunderbolt
~Hidden Power (Fighting)
~Mismagius is my ghost type pokemon to null out the fighting and normal type moves. Standard Set, but I am thinking of making it a Calm Mind setup with Shadow Ball and Hidden Power (Fightning) to hit everything.
Clefable @ Toxic Orb
Nature: Calm
Ability: Magic Guard
EVs: 252 HP / 252 Sp Def / 6 Def
Moves:
~Encore
~Thunder Wave
~Facade
~Softboiled
~Clefable is a beast. No SR, Spike, or any other residual damage is dealt to this thing. T-wave is for crippling anything in it's path. Facade for a powerful move with Toxic Orb. Softboiled to regain HP and Encore is just amazing for any poke that tries to set up.
Swellow @ Flame Orb
Nature: Jolly
Ability: Guts
EVs: 252 Atk / 252 Speed / 6 HP
Moves:
~Quick Attack
~Brave Bird
~Facade
~U-turn
~Swellow is arguably the best possible sweeper in UU. Guts makes this thing super strong. I found Protect just to be a waste of a turn as most people either expect it or I need to hit something. Quick Attack fills in Protect's spot for Priority and STAB.
Threat List:
Shaymins of all types
Drapions
Rain Dance Teams
And more but I can't think of any right now
Conclusion:
I feel this team is really solid but it can't answer certain threats well enough for my liking. I'd like to throw in Hitmontop or another good Fighting type on this team as well as another good wall but I don't know what to cut and what to tweak. I'd also like to be able to set up Spikes or SR. I also would like to keep Slowbro, Clefable, and Venomoth on the team no matter what. Thanks in advanced.
