I think the best way to win with Freaks is with 8 power guys, and there best 8 power guys are Bogdan, Baldovino, Olga, and Grudj.
The problem is that is a 16 star 1/2 deck.
The other 1/2 of the deck needs to probably be 2, 2, 2, 3.
So if you go mono-Freaks, Hula, Soushee, Esmeralda, and Akendram would be my choices.
If you go with a 1/2 deck, I would look at La Junta or Sakrohm (Dean, Winston, Wardog, Jane Ramba, Murray, Na Boh, Wakai, Nimestiec). I would probably lean towards Sakrohm because the pill forcing nature of their ability and the life gain work well with the Freaks.
Bogdan baldovino olga and esmerelda is the best half deck for freaks ATM, finding a strong half deck to work with them is the key. I suggest either sakrohm or some other attack manip low star count half deck
I've been using Grudj, Bogdan, Olga and Soushee this last week. It has been working just fine I guess. Then I make another strong half deck with any other clan and that's it love their cards for the solid power and good abilities, but the bonus only works once
