Has anybody tried any draft format with CoC? I think CoC would work best as a draft of all LCG because CoC has amazing resource system for drafts. Something simple like this might work:
Get 2 Core sets and 4 players. Divide cards from core sets to 8 piles. One pile for each faction (so 7 factions) and 1 for neutral cards. Shuffle the piles. Now every player draws 2 cards from each pile. Everybody should have 16 cards in hand. This hand is the "draft booster pack". Draft the "booster pack" normally as in other CCGs. Do this "booster pack" drafting 3 times. Now everyone has 48 cards. Players make 30 card deck out of the drafted 48 cards. Games works as normal games with one expectation: player doesn't lose if his library is empty.
Then everyone plays one game againt every player (so 3 games for everybody). Everybody gets 1 point for each story they win and 2 points for winning the game. Total the points and determine the winner.
