So how do you guys do draft?

Is there a way I have all these draft cards but not sure really how to draft should I create like a draft group of cards and then use thouse cards to draft?

We had a draft tournament back in October of last year. You can read all about it here.

We basically had 6 guys go in on a core set and one of each of the deluxe expansions and assigned everyone a faction, giving them all the cards of that race.

We then separated out all the neutral cards into equal stacks roughly the size of a pack of magic cards(I can't remember how many were in each stack) and drafted from these.

The great thing about this was it gave new players all the cards from 1 faction so they could jump straight into buying battle packs. They only down side was it ended up costing around $26 a person(with $5 figured in for prizes).

I really wish there was some sort of draft kits available that would be around $15 a person.

 I proposed a 6 player draft method here javascript:void(0);/*1329575941005*/ 

There are also draft methods mentioned in the rules and in BGG forums under variants.
