Magic on Tap

Whenever a player is dealt combat damage, that player pours a drink. (To pour a drink, exile the top card of your library and put a drink counter on it.)

Whenever a player deals combat damage to another player, the attacking player may take a drink. (To take a drink, play any card from exile with a drink counter on it without paying its mana cost.)

{10}: For each drink in exile, take that drink.
