ok so i got jetfire as starting s-card. got megs and devastator also. don't have credit card so cant buy shit, and will have to wait level 40 for sideswipe. now how to upgrade cards? is there any hint, i.e. like tfl when you have to max, trans-scan and then max again? or i just promote cards with some stars, and then develop as much as i can? i feel dumb as fuck now.
