Neera, Wild Mage (Battle for Baldur's Gate Promos 288s) - Date Stamped - Rare Magic: The Gathering Card

Whenever you cast a spell, you may put it on the bottom of its owner's library. If you do, reveal cards from the top of your library until you reveal a nonland card. You may cast that card without paying its mana cost. Then put all revealed cards not cast this way on the bottom of your library in a random order. This ability triggers only once each turn.
