haha i found out how it worksthe less credits you have the more likely you will be to get a GOOD hero..
WHY? you ask?
simple say the hero costs 3m credits and you have 250k then it will give you the hero.. hoping you go buy that nice 100 gem costing chest..
and since i know this rolling just b4 lady or during lady is your BEST bet @ getting new GOOD heroes..


the less credits you have the more likely you will be to get a GOOD hero..

My best luck with getting heroes and hero cards has been righht after rest. But it is a roll of the dice every time, and what works for me is not likely to work for everyone. If what you have found works well for you, then do it and I hope you get good heros out of it. But it may just be pure luck.
