7 star cards

How rare are they and how many of them are in the game currently? Also, If I started in the rookie part of the event and go pass 30, am I not eligible for rookie rewards anymore?

I just saw this card and deployed her as an ally... pretty...

Spoiler:

I gotta say though, they should have draw her head angled a little bit to the right.  Her looking straight forward while orienting her torso to the right, but maintaining straight legs really makes it look a little awkward.

Especially her  

they are quite rare
but there has to be at least 15-20 of her out there now
expect to pay up a large sum of TE/$$ if you wanna get her though
I saw one person selling for 5K TE pure

If I pulled her I would totally trade her for either Georgios 1:1 or Ehtel+Francois 1:1
Frejya's price will "plummet" after a couple of new 7*s get released. (will still be extremely expensive though)
