Arwen Undómiel

When Arwen Undomiel enters the battlefield,
look in your library for a card named Rivendell
and put in your hand.
Ward {2} (Whenever this creature becomes the target
of a spell or ability an opponent controls, counter it
unless that player pays 2.)
Whenever you cast an elf spell spell, you draw a
card and you gain life equal to Arwen's power.
