What happens when you've bought all the upgrade cards?
Has anyone reached the end of upgrade cards? Is that even possible? What happens when all the upgrade cards have been bought and all max capacities have been reached?
I've got all the individual upgrades currently out (though it seems we may get a few more to choose from soon), and my deck is now all energy upgrades with the odd get-out-of-hell or reshuffle card. I haven't upped my energy tank much (am at 3600), so am not sure whether those ever run out. Given that a couple of folks have tanks of over 30,000, it may be a long while (if ever) before you wipe out your deck.
