There's another similar Drafting Method already out there, however, with the one I came up with, you won't be passing decks back and forth between players, such being able to monitor which cards your opponent took. Tell me, what you think of it:
First, shuffle the Mage-Cards, each Player draws one. Put the others aside without looking at them. Now look at the card you drew: this is the caracter you will be building a Spellbook for. Or, alternatively, if you have two Core-Sets available, each Player may choose his Mage (secretely).
Seperate all the cards into Categories: Creatures, Equipment, Attacks, Enchantments, Incantations, Conjurations. Shuffle each deck. Then work through all the Categories, using the following rules:
1. Deal 10 cards to each player.
2. Each Player chooses 5, then puts the other 5 on a discard pile.
3. If at one point there aren't enough cards on the pile left to deal 10 cards to each player, shuffle the remaining cards with the discard pile.
3. Repeat Steps 1+2 (and 3) for each category, until each player has a certain amount of cards: Creatures (20), Attacks (15), Equipment (15), Enchantments (25), Incantations (25), Conjurations (20) = 120 cards.
Now build your Spellbook according to the rules, by throwing out cards you don't need/can't use. Best/fastest way to do this, is by counting your maximum Spellpoints for each category seperately, then write them down, then start to calculate.
Haven't had the chance to test this yet, though.
So chances are, this method may suck (or might be optimized).
