Pay 2 to choose a character. Until the end of the phase, Richard Upton Pickman gains the character's keywords and triggered abilities. Then, treat that character as though its printed text box were blank until the end of the phase.
what is a "triggered ability"?
Does this ability exhaust since he has to pay to use it?
Can the defending player use it, or is it only applied to the offensive player?
This card seems extremely over-balanced in the hands of the defender, since there is no way to determine which of your cards he will blank and take.
