Better mystic to r2?

Burrito2525

I pulled an r2 gem and unfortunately still can’t pull doom as a 6*. Should I r2 source supreme or someone else?

For context, I also have doom and clair as r5 and every mystic as a 5*, don’t need anyone for content, just overal usage.

Sassy or mojo for big burst damage and some utilities better than sorcerer
