Eko, the Alchemist

If you would draw a card, you may instead choose land or nonland and reveal cards from the top of your library until you reveal a card of the chosen kind. Put that card into your hand and put all other cards revealed this way on the bottom of your library in any order.
You may play cards face-down from your hand by paying mana on top of them. You may manifest these cards any time they could be cast normally.
