So much of the game strategy revolves around trade (money). If you remove this aspect of the game at the beginning it would destroy the value of too many cards. The 10 starting cards (vipers and Scouts) would be completely useless cards.
i see where your confusion is coming from, im not saying draft straight to your play deck, that would totally remove the deckbuilding aspect. i was sugesting drafting to a personal pool of cards that forms your own buy row to buy cards from. you still start with your standard 10 cards and still have to buy any card you put in your actual deck.
i was just curious if the 4 groups were roughly equal to make this a reasonable way to play.
