Reveal the top three cards of your library. Target opponent may choose to put those cards into your hand. If they don't, put those cards into your graveyard and draw five cards.
Before signing anything on Grixis, always read the fine print.

The targeted opponent has two options: Let you have the three revealed cards or let you have five unknown cards. Note that if the opponent goes with the first option, you put cards into your hand rather than draw them (in case something like Hoofprints of the Stag cares about that), but if the opponent goes with the second option, you actually draw cards.
