Pussycats, Gheist, junkz... who knows...
The best Freaks decks I've ever made were only Freaks. However, that was before Type 1 & 2 formats, so I would probably use either a Freaks/Nightmare or Freaks/Gheist deck now.
Freaks / Uppers
Miss Ming *1

Simple strategy, all Freaks are bait cards and are meant to die, but if they have damage reduction, add pills so make sure the Freaks bonus takes effect. Alot of combo cards, 2 Stop Opp Ability and a damage reduction, and 3 8 power cards against the All Stars. Uppers are expensive but playing them properly is priceless.
