There is a MTG drinking game, where you have a shared deck of 200 - 400 all mixed cards "no lands"
As there are no lands in this type, lay a card face down on the field, this now works as a all mana type card.
Its an interesting way to play MTG as you are now forced to chose which cards you will be using as mana, thus loosing what ever creature, spell or item. That was on that card.
where this can turn into a drinking game, is with every damage that you recive, you take a sip, and every life you gain you can give a sip away.
If people are interested I can bring the big MTG deck that I will be playing this very game with at Furtastic.
