Rise of the Witch King

You may pay 3 life and exile a creature card, an instant card, a sorcery card, an artifact or enchantment card, and a land card from your
hand rather than pay Rise of the Witch King's mana cost.
Search your library for a creature card, an instant card, a sorcery card, an artifact or enchantment card, and a land card. Reveal those cards and put them into your hand. Then shuffle your library.
