Fuzz is awesome, I should consider him. What about Lena actually? Louise is a VERY good card, because of her raw stats. Shes basically a tan man cr with one less power. I like to use her as a threat to 6 powered cards. She is also GREAT on a 3-1 draw, because her bonus doesnt help her win the match. 3 Junkz and a Louise means you can nuke when you choose and have an advantage (usually) in the first 8 pills. Soa hurts her, but she can be used to call bluffs even so against most SOA cards. just 36 attack her agaisnt Roots and GHEIST with 7 power. She also can threaten with KO. Honestly i am so in love with the card, i even prefer her over Lena on days where theres not alot of Bangers (although, id say she does well against almost any clan). Bristone and Jeena and Yookie and Bogdan are her best counters, however who dont those cards counter xD
I prefer Lena over the other Cats 5* for 1/2, Protection A/B is a great ability for a 5* character to have, but it's no contest that the Junkz 5* are far superior, such as Peeler or Taham. Also you should try Jiro, he is one of the best reasons to use Junkz. I would not use Diana, she seems underpowered.
