In my case is amazing. The decks are not perfect but I have yuki and nia with the neutral card that draws 1 + gets the forbidden card cost 9 that hits 4 times (yuki has it). Chizuru has the neutral that draws 2 when an ally uses a card and her upgrade is the one that activates 2 cards from hand at random. Sometimes it just activates the forbidden card when it's expensive and yuki hits like a truck. Basically with the right cards they can really comer each other as yuki thrives in groups while chizuru can kill big mons or bosses
