Maiden or Angel?

Lately, I've been trying to save tickets, so I'm only using the daily boost, but I still managed to get another surprising unique name drop ✨️ "Valkyrie Angel"... It's a name that makes you want to ask, "Which one is it?" but well, since the original is Valkyrie, I guess it can't be helped lol But can't I use its skills and abilities almost the same as Valkyrie? 😳 The Angel's unique skills are just Mental Fortitude (mental resistance), Resurrection (revives one fallen ally once), and Radiance (grants all allies dark resistance). Even so, this unit itself is Rank C, so it's easier to strengthen and raise than the Rank A Valkyrie! ✨️ I'm thinking of using it as a light archer from the back row when needed 😊 Well, there's always the problem of the back row being a bit crowded with members... lol
