Edit: No, I'm wrong. If their library has more cards in it than yours, you're dead. If they have less, which is quite probable considering combo decks proclivity for cantrips, well, hopefully you can kill them in a couple turns.
More like:
"Draw cards equal to the cards in your opponent's deck"; which may be instant-kill, or pass-the-turn win, or 2-3 turns to decking; depending on how deep the Notion Thief player is into his deck. Brainstorm + Enter the Infinite is likely instant kill.
