When we started using the expert culling rule in Quarriors, we found a confusing interaction with the Deathdealer. It's special ability is:
When Deathdealer scores, you may trade Deathdealer for one die from any other player's Used Pile.
However, the expert culling rule says that you can only score a creature if you cull that creature's die. How can you swap it and cull it?
