Will the Academy cards be part of the current database, or will they be coded into a separate Academy-only database?
What I'd like to see is Academy cards in the regular database (since they're legal in Arena/Domination and I'd like to be able to add them to my current books - as I have in real life), but there should be an option you can click for Academy-only format. Basically give all cards a property of "Academy compatible" or not... which could be updated if any Arena cards ever become legal in Academy (if competive Academy were to become a thing that shoudl be supported).
Also, it could just be linked to your mage choice in the spell book builder. If you choose an Academy mage, the software could automatically limit you to spells that are legal in Academy, hiding all others. But perhaps keep everything visible in the (non-builder) database.
