Mana cost: {4}{U}

Legendary Artifact Creature — Android Scientist

Seek out — Whenever you draw your second card each turn, discover 4. (Exile cards from the top of your library until you exile a nonland card with mana value 4 or less. Cast it without paying its mana cost or put it into your hand. Put the rest on the bottom in a random order.)
