That deck looks decent to me. I have been using a 5/3 with Pussy cats and 3 of another clan this weeks (since I don't have Emeth or much Jungo) and it has been pretty decent. Ditha and Muse are both great when most of you deck can damage reduce.
I don't use Ella though. I find her to be awful. Her extra reduction is only useful now and then (though perhaps it is better this week with all the La Junta) and her stats are low enough that there is rarely a possibility of a surprise attack with her.
On the other hand Brittany will usually force an extra pill out of your opponent and since she has decent potential for a small surprise attack your opponent will often put an extra pill or two against her.
