They might be part of the group testing the alpha. I dont have a tourney either, but i do have the arena. The rankings is still closed off to me since its not available in the beta
EDIT: also, i think there is a specific hour each day that the price of the gem gacha changes. This morning it was 200 again, but each time i come home from work, its at 99. SO save your gems and when the price is low, thats when you buy
