Jace, the Mind Sculptor is the first planeswalker with a loyalty ability that costs 0. Activating this ability follows the same rules as activating any other planeswalker ability, though you’ll neither put loyalty counters on Jace nor remove loyalty counters from Jace to do so.
If you activate Jace’s second ability, the two cards you put on top of your library may be any two cards from your hand. They don’t have to be cards you drew with the ability.
