What should I pick with the free S Rank gift? So far I have:

>Grace at C0
>Rina at C4 (GO AWAY FLOATING HAG)
>Koleda at C1
>Neko at C1
>S11 at C0
>Lycaon at C1

For balls, the only ones I don't have are Brimstone, Weeping Cradle, and The Restrained. I'm inclined to pick Brimstone as a generic "all around" ball to replace Starlight.
