I’d attack a defense team with her any day – trigger her SS on purpose and then focus all skills aimed at her. She punishes her team when she gets KO’d while they’re dancing.
IF she is to be used on defense teams though, she’s mandatory going to want Q. of Hearts as her ally. Her taunt is drawn to her minion, meaning that Queen can still use it (Black Knight can’t though, because dance status effect prevents it).
But for titans she seems like an awesome Wu Kong / Ranvir replacement. +100% attack is a lot, and even though it’s lower than the other two and can’t stack with other buffs, there’s no miss chance either. I’ll take that gladly.
