Great thoughts - thanks for letting us know how you feel! It is our desire to provide players with all the copies they need.
We have had to make some tough choices, because if we provide plenty of each card, then the variety of cards goes down. For example, in the base set, we provided everyone with a pretty good mix of cards, and out of 322 spells, 174 are unique. If we instead included lots of copies of everything, players would have ended up with half as many different spells, or even a third.
We created the Core Spell Tome to immediately help players to get a few more of the most important spells. In the future, these "Spell Tomes" will have some NEW spells in them, but also provide additional copies of past spells.
We want your opinion please! Would you prefer these Spell Tomes to be keyed to specific Mages and schools of Magic? In this manner, if you like playing the Priestess, you could get extra copies of all of her Holy Spells, plus a few new ones.
Or would you prefer them to be keyed to a THEME. For example the Creature Rush Pack has extra copies of all of the creatures for all of the Mages?
Also, these Spell Tomes should not be confused with a Mage Expansion Set. For example, our first Mage expansion set, The Forcemaster vs. the Warlord, will come with 220 spells, the majority of them new, and all related to the new Mages. The only older duplicate spells in these sets will be a few Dispels, Minor Heals, etc. which each of them will need to help round out their spellbook.
