At the beginning of each end step, if an opponent lost 3 or more life this turn, you may draw a card. (Damage causes loss of life.)
5/1/2008 As the end step begins, Sygg’s ability checks whether a player who is currently your opponent, or a player who was your opponent at the time they left the game, has lost 3 or more life over the course of the turn. If so, the ability will trigger. If not, it won’t.
5/1/2008 It doesn’t matter how the opponent lost life or who caused it, as long as the total loss of life is 3 or more.
5/1/2008 Sygg’s ability checks only whether life was lost. It doesn’t care whether life was also gained. For example, if an opponent lost 4 life and gained 6 life during the turn, that player will have a higher life total than they started the turn with — but Sygg’s ability will trigger anyway.
5/1/2008 You don’t specify an opponent when the ability triggers. If multiple opponents have lost 3 or more life over the course of the turn, the ability will trigger only once.
5/1/2008 Sygg’s ability will trigger even if Sygg wasn’t on the battlefield at the time some or all of the life was lost.
5/1/2008 Sygg’s ability checks to see if it triggers at the end of every turn. It doesn’t have to be your turn, and it doesn’t have to be the turn of the opponent that lost life.
