@Fine - I understand where you are coming from, but they are better against those clans than you think. Sasha, Sandro, Redra and Chiara are 4 staples for Skeelz (you should only play Skeelz in mono or splash 1 or 2 at most IMO) and right there you have 1 VERY strong attack manipulation, 2 solid power manipulation and a DR and space for 15 stars for the 4 remaining slots.
That leaves you with some other options including:
Aylen - potential 12 life gap makes her one of the scariest cards out there
Belgosi - underrated 7/5 power manipulation
Cley - situational, yes, but with the other staples, it should not be hard to get a win and make him 8/6
Corvus - high power, +3 pills makes your opponent think twice before bluffing
Deebler - another situational card, but -4 damage 2 min is nothing to scoff at
Greem - one of the best poisoners in the game that is still ELO legal (although often banned)
Jay - 11 potential damage
Logan - great for getting through dr, which is always around ELO
Liam - their only SOA, but he's still won me rounds, simply because people don't expect you to pill with him
Praxie - like Logan, breaks through that annoying DR and has 8 power
Tomas - 8/6 SOB
So while they may have a lot of situational cards and many others with low damage, they make up for that in great abilities and a bonus that protects them (except all stops, but they hurt most other cards too)
That's my 2 cents.
For the record, the 2nd time I got to 1400, I was using Skeelz in mono
