A question that needs an answer

Okay, I play an academy deck. My win condition is Braingeyser+Mind Over Matter+Tolarian Academy. I played a game in which I forced my opponent to draw his entire library. He said he didn't lose yet; that he lose during his draw step. So I believed him since he was an experienced player. Recently, I did a big Prosperity and everyone drawed his entire library. I thought I would die during my draw step (after my opponent's turn so I would still win) but they told me I lose automatically. Which one do I believe? Or did the rules change somewhere?

A player looses when they have to draw a card, but are unable to. If it were the case that you automatically lost when ou had no library, cards like Leveler would be completely and utterly pointless.

If they are not able to draw the number of cards you hit them for they lose immediately.   IE :  I stroke of Genius you for 20,  you only have 19 cards left on your library and no way to add more cards to it before the resolution of the spell  then you lose.   Hell.. in the good old days, i remember dieing from being ancestral recalled by my opponent with only 2 cards left.  /blush.

Also, if a big Prosperity forces everyone to draw more than their deck, then the game is a draw, regardless of who has fewest cards in their library - just as long as everyone, at some point during the resolution of the spell, has to draw a card and can't.
