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.
I really like ur deck, I'd use Liam somehow for 1 SOA. The deck works well (I use mono-Skeelz sometimes as well), I like Skeelz for both mono and half decks. They work well w any atk man clan as well as Jungo n Berzerk. Spaigi is also a lil more useful than Redra if it helps
Good idea swapping Spiagi for Redra. Better min and power
The skeelz are very effective in elo with power and abilities but lack the damage and good In low pillz fights too
Also, give a try in manfred, hes better than jay sometimes.
I've gone over 1300 w:
And Andy Ld (sorry, I forgot him)
The deck works well, 2 dr, 3 pwr man, 2 atk man n 2 pill man (sort of)
Id like to use Liam (SOA) somehow, maybe lose Andy Ld n put the pill in somewhere else but I'm unsure who else to add. Liam is one of the most underrated Skeelz there is imo
