Covenant of Minds — ruling 1

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.
