Meh, I personally think of Yuyu as a cheaper Belinda (due to AW -1 and gold vs. plat) without the Witch buff. I don't use either much, though, due to having AW Adele and Despara (I used all 4 on War of Magic though, that map that used to be a complete nightmare was cakewalk lol). Having AW Belinda on the team if you use those two though is great (which means Yuyu becomes MUCH more situational since you already have a Range Up witch in team), and since I use both for early magic damage frequently on some maps, having their attack buffed (especially Despara since you can essentially think of her as having skill on from the get-go; 7% buff receives the 1.9 multiplier for her so her attack with Belinda and skill is over double her stats page attack, even more so with AW Aria/Uzume and Prince around)
