They do very well in a halfdeck with Chiara, Plunk, Redra and Kephren. Especially when Leviatonn, Lizbeth or Oshitsune are unbanned and many people plays SoA/SoB clans.
In mono I think they also will work great. Dr Falkenstein and Sasha have great attack that helps them to beat other attack manipulation clans. You have 2 nice DRs (Redra and Kephren) and they work amazing with Jay and Chiara Cr. You have Sandro with 10 power and Praxie with stable damage.
But I think the problem of the Skeelz is that when they meet clans without soa/sob (Pussycats, Allstars, Sakrohm) only your ability has effect while the opponent has an effective bonus and ability.
So when cards like Oshi and Leviatonn are banned, I think they are risky to use in mono. In half they will still work amazing.
