Benjamin, Electric Inventor

At the beginning of each upkeep, choose a player
who controls the most permanents with flying
or the most artifacts. Benajmin deals 3 damage to
that player or target creature that player controls.
{1}{u}: Put a flying counter on target artifact.
{1}{w}, {t}: Target player investigates.
{4}{r}, Sacrifice 5 clues: Search your library for a
non-creature spell; you may cast that spell and if
Benjamin dealt damage to you this turn, you may
cast it without paying its mana cost.
