A player, 5 July 2007
If Asako Masamichi has used his ability, but is subsequently killed and brought back into play using Hope from Death, will his ability fail to keep the affected personality bowed?
Hope from Death
Reaction: After one of your Human Personalities is destroyed during battle, pay his gold cost unless you are a Phoenix Clan player: Overlay his card on one of your target Human Personalities at the current battlefield, ignoring title and experience levels.
Asako Masamichi
Battle: Bow a target Personality opposing Masamichi with less Chi. Before this battle resolves, if Masamichi is not at the current battlefield, straighten the target.
