In the past, freaks are the most common clan used in ELO. This is mostly because they are reliable and star wise. Now that there are a lot of new clans and cards that would make a good deck in ELO, it doesn't mean that freaks are out of the picture.
In fact, freaks are one of the stable half clan part of a deck that I prefer. I believe that a good defense/offense strategy is able to lead you to victory with freaks and pussycats in your deck.
An example of a deck combination containing the two said clans above is:
Freaks are perfect for half-clan play, because while their bonus isn't great enough for a monoclan, they have some very, very good cards. Olga and Akendram are some solid 3*s, Wolfgang is a good damage reducer, and everyone loves Splata Cr, even if they can't afford him
Even Hula, with her double poison,is very hard to stop, and one of the more underrated of the "super 2*s" popping up everywhere.
Alot of their best cards are cheap too, with lets you fill the other half of your deck with the best you can afford
