Collector #:	063
Reveal the top card of your library and put that card into your hand. You lose life equal to its converted mana cost. You may repeat this process any number of times.
Pro Tip! Legacy ANT/TES takes advantage of Ad Nauseam by revealing cards with low mana costs that enable huge, one-turn combos. Modern Ad Nauseam utilizes Phyrexian Unlife or Angel's Grace to not have to worry about that pesky "If a player has 0 or less life, he or she loses the game." rule to do the same.
