I pulled a Mystic gem during Cyber Week. I had been holding it for Isophyne in case she was very good and in case I didn’t pull spiral - wanted the Serpent Counter. However, since she is solid but not outstanding, and since we’re likely to get the dup from the realm event, and since I pulled Spiral from the holiday gift today, I’m now trying to decide who to use it on.
Here are my R2 and R3 Mystic champs:

Lead candidates are The Hood, Spiral, Cow, and Juggs. Right now I’m leaning towards The Hood as I feel like his gets the most benefit from his sig ability. I do have some stones I can put into whoever I end up awakening. That said, since I just pulled Spiral today I don’t know enough about her yet to know if I should be looking at her instead. Cow could be a good option as it improves him from a defense standpoint, but I’ve already learned with my 6* that I don’t want him to ever get to high sig, and I’ve seen enough people say he’s almost better not awakened. Juggs I’d like to get awakened but feel like he and Cow get the least benefit from it. He’s also in the basic pool.
Juggs and Cow are already R3. Only reason Spiral isn’t R3 is that I want to play around with her some before I pull the trigger, and I am also reluctant to R3 her with the special bug. But eventually both she and The Hood are going to be R3 as well - mystic is my favorite class.
So what do you all think?
