Any phase: Bring Jaqen H'ghar out of Shadows by paying the rest of his cost to choose 1 non-Army character in an opponent's dead pile that was killed this phase, and attach it to Jaqen H'ghar as a duplicate. Jaqen H'ghar gains the printed text, base STR, icons, traits and crests of that card. If that duplicate leaves play, return Jaqen H'ghar to Shadows.
