Sir the lord of the nerds

Power of the Nerds — Sir Lord of Nerds gains all abilities of other creatures you control that are also nerds.
Lorekeeper's Knowledge — Whenever Sir Lord of Nerds enters the battlefield or becomes tapped, you may reveal the top card of your library. If it's a non-creature non-land card, you may cast it this turn without paying its mana cost.
"He's been to every plane, read every book, and leveled up every stat. You don’t want to face him in a duel."
