I have a few questions about upgrades.
I figure in order to be fairly competitive you would want certain upgrades for the ships that you own. Since many upgrades are not ship specific, are you allowed to announce you are playing a particular upgrade card if you do not actually have it?
Since you can see all the various upgrades available on various sites across the interwebs, are you allowed to make your own cards or just jot down the pertinent stats and use them in building squadrons with the ships you own even though the upgrade is only available in an expansion you don't own?
Is that considered a no-no or uncool?
