Did you hatch a Gremoris? That resets the pity counter.
Also during anniversary you should not use your regular gems on the gold egg, just the tickets imo. Unless you’re a big spender? There will be more banners coming with better odds, including a second anniversary banner and new mythic next Friday!
I wanted a awaken the mythic. Used purple steller key but got nothing. Then thought will do hatch 10 but after 3 times revised it not worth it now but when I checked the pity it was 30.
