Durnan of the Yawning Portal (CLB-657) - Commander Legends: Battle for Baldur's Gate Foil

Whenever Durnan 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 less to cast for each opponent.)
