What character has been your best pull so far?

As in, which character that you pulled for has been the one doing most of the heavy lifting in your fights and basically you can't seem to not be able to have them on your teams due to how good they are?

In my case it is Camellya.

I only got one copy of her and that was at max pity, but she makes things much easier for me when fighting, specially when she goes "red hair mode(I keep forgetting the name of this)" where I can just hold the attack button and she keeps whipping around hitting everything while "on air".

She's that convenient, specially since be it either due to my mouse or my lacking timing skills, but I keep not beinh able to counter boss attacks normally.So I use Camellya since her constant whipping attack makes it much easier to hit the circle.
