Magic on Tap

Whenever a player is dealt combat damage, they
pour a drink at the beginning of the next end step. (To pour a drink, exile the top card of your library
and put a drink counter on it.)

Whenever a player deals 5 or more 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 mana.)

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