you may need to clean your cache but first spam arena. The one I did last time I did it in one go. oh and see if the event cards have steroids cuz that's what I used.
I will clean cache and cookies to be sure, thanks. And yes, I always use cards with Steroids before of any other card, even if that means losing the match... I do it on purpose to unlock that frigging step of the event. Thanks anyway!
