Well the answer would be the same for any summoned monster. The Mask states that when you encounter a monster, display the mask and put the monster on top of it. Not defeated or undefeated. Complete your turn. Then it says to put the monster card on top of the location deck. Well you can't do that with summoned monsters, so the card would be banished back to the box and the mask would be buried under the character card.
