Kristen Parker, Dream Bridge

Whenever Kristen attacks, look at the top four cards of
your library. You may exile a creature card from among
them. Put the rest on the bottom of your library in
any order. For as long as that card remains exiled, you
may cast it. That spell has undaunted.(It costs {1} less to
cast for each opponent.)
Fall Asleep- When this creature dies, exile it.
You may cast the Spell side of this card.
"I'm going to dream you into a beautiful dream."
- Kristen, to a dying Nancy
