Earlier today, right after calender rewards to be exact, I got really awesomely lucky when I formed my bi-weekly Grandmaster shard crystal. I was so excited, I didn't think to grab a picture, but here is my alliances board showing my luck. I immediately went to rank2 with my "miracle champ"!!

But the luck didn't end there. A few minutes ago, I did my 4th unstable epic rift. Crazy huh?

So I'm pretty sure who I'm supposed to use it on, but I just want to see if the community has any feedback. I would hate to use it on the wrong champ and regret it later. I only have 4 5* Mystic champs, and one of them is already duped by pulling her twice.

So I'd appreciate any feedback you guys might have.
