Gengar @ black sludge
Nature: timid
Ability: levitate
EVs:110hp 230spd 230spatk
Moves: hypnosis
Stealth rock
Nightmare
Dark pulse
Turn.1 hypnosis the opponent can't move If the opponent wakes up redo turn 1 and 2
Turn.2 if hypnosis hits use nightmare
Turn.3-5 use stealth rock
Turn.6 use dark pulse
When the opponent faints use turns 1-2-6
He is also protected from trick unless it is part poison type and even if he does get tricked by a non poison type every turn they will get damaged if it is part poison type than I have a problem
(Footnote: I only use this strategy in competitive battles/hard battles
