Clara, Squeaky Navigator

Flying

Whenever Clara deals combat damage to a
player, that player exiles cards from the top of
their library until they exile an instant or
sorcery card. You may cast it without paying
its mana cost. Put rest of the exiled cards on
the bottom of their library in a random order.
