Thunderdome

When this card is played the player challenges any other player to a duel.
As the lords of Bartertown Aaron and Tam will
decide the challenge and its parameters.
The winner takes both books and may take one
of the books out of play.
Max: Thunderdome. How do I get in there?
Aunty Entity: That's easy. Pick a fight!
Two books enter! One book leaves!
