Jace's Deep

When Jace's Deep enters the battlefield, sacrifice it unless you return a non-Lair land you control to its owner's hand.
{2}{u}{u}, {t}, Sacrifice Jace's Deep: Exile target blue planeswalker you control. Return that card to the battlefield under its owner's control at the beginning of the next end step with two additional loyalty counters on it. Activate this ability only any time you could cast a sorcery.
