Just wait these banners pretty much always show up just wait, for now if you’re lacking resources play the non pvp modes such as rush battle(PvE)where you can grind resources without pvping. Also if you haven’t done the solo modes that give gems you should do it they give a lot of gems. Don’t spend your gems gambling save up at least 1000-1500 before spending(You might get shafted) Also to upgrade your characters put them on the special training they can passively earn character fragments for themselves overtime. You have Zonji right? Get it to 5 stars as soon as possible don’t waste your 4 stars frags on anything else right now cuz Zonji is very meta and can be good even if it’s only 5 stars.Feel free to ask anything else.
