Hexproof, menace
Whenever an opponent reveals one or more cards from his or her hand, draw a card.
{2}{u}{b}: Name a nonland card. Target player reveals his or her hand. That player exiles a card with that name. You may cast that card for as long as it remains exiled, and you may spend mana as though it were mana of any type to cast that spell.
