I was playing in BR and kept getting poisoned by Gliscor the match went the full 45 min and we were each down to the our last prize cards, that whole match I did not roll one heads. Even on moves like triple attack.
My daughter is 9 and has been doing ok with trades she can get some good stuff for almost nothing but most of the stuff is beat up or old. I suggested she asks about trainers and supporters. I am betting that kids who dont play do not put any value on those.
