Which 6* Mystic to awaken?

I have a 6* mystic awakening gem, and just looking for advice on who to use it on, or to save it for better champs. Below are my current options.

I regularly use my R3 Purgatory and R2 Sasquatch, but I don't really use any of my others. Any advice is appreciated.

Save it

For rintrah

Voodoo, though mojo is good if you want to invest stones.

Thanks. I think I'm going to save it for now. Wait for someone who definitely needs it.

I'd go for Mojo. Since he we have champs with timed buff like Sersi, Gorr and Hulking, Mojo's value has increase even more nowadays.
