This is just an idea for those of us who are stuck with a single core set for a while and who have friends playing without a set of their own.
Since the only resource you're really limited with if two (or more) people play with one core set are the command cards I think it's fair to have a way for each player to get the cards they want without upsetting the other player(s).
The solution (I think) is a draft mini-game that would work like this:
1. Each player after picking a faction takes the three command cards specific to that faction (note one of the Chaos specific cards does not have the chaos icon in it but it only works for Demonic creatures, so its purpose is clear). If each player plays two factions they get all six of those cards.
2. The rest of the command cards are shuffled and split into two piles (face down). If you have more players participating, split to three or four piles respectively.
3. Each player then takes a pile, looks at the cards, picks one (hidden from the others) and passes the pile to the next player.
4. After all the cards are distributed, each player decides which of the picked cards would be used (up to their command deck size) and discards the rest face down (so no one knows what the others have discarded)
This way everybody gets a chance to get what they need and still no one is sure what the others got until each command has been played. Also with the three faction-specific cards being distributed to players outside the draft, there's much less opportunities for hate-drafting and also makes for faster drafts (only 12 cards are drafted).
For two player games where one is playing Order and the other is Destruction, you may deal the Order Only and Destruction Only cards along with the faction specific ones at the start and get the number of draft cards down to 10.
What do you think? Fair? Any potential for abuse? Am I missing something?
