Lucky or not?

Not too bad actually. Fae is a nice anti meta unit that can stop Reinhardt and Brave Lyn cold if built properly, Delthea is (almost) as good of a nuke as Reinhardt is, Genny is fodder for Wrathful Staff if you happen to have a good staff user, and Gray can work well with a Brave Sword build. Better four 5* heroes than none at all.

Delthea is an amazing unit, her base attack is beastly. I'd say for 60 orbs you have been lucky, Fae, Gray and Genny are also worthwhile units. You're lucky you didn't get your pity rate broken by Peri or Merric.

i'd say your lucky ^^ at 4.5% rate in CYL banner and no 5* after all those orbs
