Now this has been a favorite of mine on the forums for 8 years, so I can't wait to see your ideas!

Hmm 7/2 is not ELO ban worthy. Lehane literally got unbanned a week ago and she's 8/2 SOB with a better 2* bonus than Valentina, she can wall better. At the very least 7/2 or 6/3 would not be banned, maybe if the staff have double standards for All Stars cards to Sentinel she'd be banned at 8/2.
And tbh, the staff do make All Stars SOB so weak for no reason. 5/2 2* Flo SOB when Lehane is 8/2 better bonus, and most clans will have either 6/2 or 7/2 SOB. Lamar Cr was the big 5* of the clan for a long time while other clans had Guru Cr and Vickie Cr.
And very weirdly, All Stars has 2 terrible 4* SOB. So uncommon Liu is 5/7 courage SOB, and rare Heartnett is 6/6 reprisal SOB, while common Bangers Chlora is 6/6 SOB no condition... what? Of course AS SOB won't be as strong as 4* Quetzal Cr 8/6 SOB thats fine. But even other reprisal SOB 4* like Bridge is 7/6, it makes my brain confused. I remember when Heartnett was first released, he was supposed to be baby Lamar IDK why he wasn't just 6/6 SOB no condition.
The FPC card is balanced actually, not OP or meh. It's very similar to Gonzo except Gonzo has a better bonus that will help him keep his ability, while Yan has slightly more potential. Yan is 8/3 on win +3 on defeat, and fury will make his DR stronger, but he will get nerfed by SOA, SOB, damage reduction while Gonzo is 8/3 on win +2 on defeat, and fury does nothing, but he will not get nerfed by SOB or DR. It's pretty good
