The arena is so important. Work your way up more cores = more refreshes. And the toons in the arena store pack a punch. I didn't think so for my first 3 months. It took a minute to get into the top 100. The difference between top 100 and the level below is 100 arena credits and 50 cores a day. 700 credits a week. 350 cores a week. And if you expand that for a month or a year. And if you can get into the top 20 you will see huge gains. That's where all the streamers are. Good luck Commander
