Captain Alyssa Prell

Whenever a spell is cast from a graveyard or from exile, this creature deals 1 damage to any target.
Whenever this creature deals damage to a player,
exile the top card of their library unless they let
you create a Treasure token. You may cast cards
exiled this way and you may spend mana as if it
were mana of any color in order to cast them.

trouble? Don't worry, I can fix him up."
