you can complete achievements and save tokens as much you can for good enhancements. If you play every day, you can get daily 5 wins. With the 5 wins as minimal, you get 10 tokens plus silver coins to enhance your account arena items as caps, resistance, base etc. Saving tokens is something good if you are free to play. Now, if you will be a pay to play, so buy anytime plus doing daily will give you extra. commercials are limited. I think 30 per day equal to 60 tokens or used to be like that. Never worked in my accounts on tokens base commercial wise I do not know why. Sure, I get commercials all the time but can use 30 at any time then will go away and have to wait again. It will reset next day. My commercials are the same but based only on gold when I will or lose a pvp. I can choose to use it or not, I preserve 5 for the 5 wins to collect more gold and the silver tokens for fun. I can use those commercials to collect the extra card for possible epic when I craft parts using the base.
I can get 2 tokens commercial when I fight raid and lose one time a day per raid. So, 6 raid loses can give 12 tokens max per week in my account but normally because I am tired and want to be killed and move on and do not collect unless is a failure.
