According to this site, Mints (the currency type) primarily come from Battlez. You need them to buy and upgrade them. That sounds like a painful process to me. If they're anything like leveling up the regular plants, it's easy at first, but leveling up later levels goes up exponentially in terms of "XP" cost.
