Well keeping in mind the pussycats are a very defensive clan it is good to use a clan that can build off of it. I can give you probably the best three to use (although any are viable):
In no particular order
Frozn - with their easy to activate revenge bonus they hit hard while the pussycats defend
Freaks - If you manage to get poison across it is easy to maintain an advantage when the opponent is losing two life every turn and you block two of their damages.
Vortex - As odd as it seems vortex and their ability to make big plays while bouncing back from a defeat is very useful. Combining two clans that thrive off of losing rounds is a good way to make the most out of plays that don't go your way.
Thank you I really appreciate it, I'll check them all out!
There's actually four collectors.
-Frozn are best as mentioned
-Berzerk are also good as they have strong power,and their bonus backs up the pussycats low damage
I know there's 4, I have Cassio the other really expensive 3 I can no way afford
I'd say Uppers and their pill forcing bonus is a good split with Pussycats
Surprised no one has mentioned hurrican. They combo great together especially in Elo!
I would suggest Uppers as well, I run an Uppers/Pussycats deck and do very well with it.
Sarkrohm are waaaay better then uppers with pussies, no need to explain the synergy does so for its self.
Anyways, if your playing pussies you should go on the defensive will still being able to dish damage.
sorta something like a midrange deck, offensive but has the stuff to shut down and defend.
the best type of defense has been and will always be combinations of SOA+DR. unfortunately most cards with this insane combo are perma banned. (Yayoi Arno Bristone, Etc)
Since I like playing defensively switching to an offensive clan (like nightmare) wasnt gonna cut it
To counter not having SOA+DR cards in Elo I tried many other combinations and found DR+life gain to be another affective combo.
I found Ulu Watu great for this as they have walls for days!, Life gainers and amazing fillers cards that just so happen to have DR and life gain.
To sum up this long post that many might disagree with
top three clans to use with pussies in Elo (as of now)
1. Ulu Watu
