Rahilda, Wanted Cutthroat // Rahilda, Feral Outlaw

Double strike
When Rahilda, Feral Outlaw deals combat damage to a player, exile a nonland card from their library at random. During any turn you attacked with a Wolf or Werewolf, you may cast that card and you may spend mana as though it were mana of any color to cast that spell.
Nightbound (If a player casts at least two spells during their own turn, it becomes day next turn.)
