I'm a complete stranger to the entire Pussy Cats Clan and I'm seeking guidance on which cards are worth investing in and which ones to stay away from! Thanks so much.

I'm not a pro with the pussies but at least i know some good cards.
IMO you should buy
Muze
Diana
( almost all their 5 stars are actually usable)
Clover
Cherry
Ditha
Jayzel is also nice
Lucy
Veronica

that's all i can think of

Go for the standard cards. In my opinion, the worst they have in them is Candice. Who isn't nearly as horrible as some of the newer cards *cough*Rhody*cough.

+1 to both of the above suggestions. I personally like how full pussy deck makes Muze/Cherry that much more effective (even when you overpill)

pussy cats also have some very good 2* cards so they can be real good fillers
