Legendary Creature — Snail Advisor, {2}{B}{G}
Oracle Text
If you would draw a card, you may instead choose mana base, removal, or win condition 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 the rest on the bottom of your library in a random order. (Mana base cards add mana. Removal cards are instants and sorceries that can damage, destroy, or exile opposing permanents. Win conditions cost 6 or more mana.)
