The Shrinking Eels

Legendary spells you cast cost {1} less to cast. Exile two legendary cards from your graveyard: Until end of turn, each legendary card in your graveyard gains "You may play this card from
your graveyard."
Do you know what that sound is, Highness?
Those are the shrieking eels! If you don't believe
me, just wait. They always grow louder when
they're about to feed on human flesh!
