When I first read Kingprotea Alters kit I was a little concerned about how it would all come together, but after using her a bit I think it actually works pretty well.
She's not like, crazy or the best unit ever, but because of a lot of little things I would say she's quite above average.
The card shuffle being separate from her charge is great, and I think having the ability to utilize the often unused MC skills is smart.
I do wish her 2nd skill gave charge even if it didn't actually drain anything, or if she had buff removal resistance, but overall I think she's pretty good.
The only real problem I have is I have no grails, but I want to (and will) 120 both KP and KPA.
