Version 16 Preview and Progress Report

Version 16 is progressing nicely! Among other things, I added:

• Offline mode to AI battles, since it doesn't make sense for a 1v1 AI battle to need a server
• Started working on 3D game boards
• Simplified rules for Armor and Guardians
• Added a new UI
• Keyword reminders on cards
• Many other small bug fixes/changes

I'm hoping I'll be able to release the new patch around Saturday or Sunday. I hope you will like the new ways the game plays now!
