Rahilda, Feral Outlaw

Double strike
When Rahilda, Feral Outlaw deals combat
damage to a player, seek a nonland card from
their library, but instead of putting it into your
hand, exile it. During any turn you attacked with
a Wolf or Werewolf, you may cast that card and
you may spend mana as if it were mana of any
color to cast that spell.
