Draft! 3 unopened booster packs per person. Everyone opens up a pack, picks a card, and passes to the right. Keep doing that until all the cards are gone. Then everyone opens a new deck, and passes to the left this time. Repeat for the third deck, going right. Minimum deck size is 40. This eliminates any sort of monetary advantage and privileges people who can come up with good deck combinations on the fly.

If you like the deckbuilding mechanic without the collectible aspect, you might like games like Dominion.
