Eddie is a must in a setup like this. He has great synergy with Pussycats. I would drop Eugene and Felicia for Eddie and Dave.
Oraya is powerful but predictable. She might work okay in a setup like this, but you really have to think about whether she is the 5* you want. Stanley with Confidence is almost unstoppable, and you might be able to sneak him in on a turn where you don't have it. Hikiyousan is a very solid card, capable of winning rounds where needed.
