Destiny Bond should be mentioned in other options. Makes pokemon like Croagunk or Stunky think twice before Sucker Punching, allowing you to effectively KO them with Thunderbolt. The set I use is:
Misdreavus @ Life Orb
36 Attack, 236 Speed, 236 Sp. Attack
It's especially helpful if you want to lure Munchlax for a KO, or just don't want Stunky/ Croagunk playing eternal mindgames with you.
