How do you steal a Costume card from another monster?
Several posters agree on three claws plus the energy payment; the Zombie case is debated, and there is no official ruling.
Roll at least three claws that deal at least 1 damage to the owner, then pay the owner the costume's energy cost. Damage reduced to 0, for example by Robot, blocks the steal. Cost reducers such as Alien Origin do not apply. The Zombie is a grey area, but three claws that could hit its owner is the intent.
