Opened Phoenix, even though she was not advertised in LT’S in game, and stated release date is 11/12.
Was opening some hoarded LT’S early specifically to have a higher chance at an existing 5* before the specific chances decreased.
Could I trade my Phoenix cover for an SS cover? 
Is that even possible?
This post is legit. A guy in my alliancd got the purple Phoenix cover a day early as well. It’s a glitch and some people are getting seriously lucky.
You can try to ask for a do-over from customer service, I guess, but I doubt they’d give you a 5* cover of your choice.
The worst thing they can do is say “no”.
