Imo mono cats is not really strong, but they are good in a biclan deck like Survivor defence
You can alter this deck with selina louis and even ditha, or change the leader according to your preference.
would be my go at this Deckplan. In most matchups, you try to win by creating a big enough gap by winning one round and reducing in the other 3 or just outpill them with Morphun while they try to break through the Reducers.
I'm still not a fan of pussycats because too many key cards lack high power and SoA resistance. DItha is crucial for the deck but having only 7 power will force you to play incredible carefully and calculating, same with Charlie, which puts two of Pussies main-gapcreators at 7 power which is not that great for a Clan with a non-combat bonus. On the other hand, you gain a deck, which can easily win most matches by winning a single round at the right timing.
If ELO type i really like this deck for Survivor. Play Yookie over rico in the weeks Yookie is not banned. Play Arno over jeto if you like. Ive used it to get past 1300 in elo and my highest survivor streak of 12 or 13.
