Battle tower rewards?

Is it normal that I can’t battle more then 7 times in a row at battle tower? And it just keeps giving me rare candies. Do I need to battle more or have my rank up at championship ?

You need to battle more of those 7 times in a row victories. Eventually, the rewards get better, to the eventual 2x Rare Candies and 1x Dream Mist and then to 3x Rare Candies, 2x Dream Mists, and 1x IV Stone. Don’t know if it gets better than that because I haven’t gotten beyond that (mostly because some BS usually ends up defeating me and resetting my streak).

Oh, well, that will be hard. But thanks anyway.
