Her ability can only move cards from the ash heap that were played in the normal manner. If the card was put in play in some other way, it cannot be retrieved by her special.

A card canceled as it is played is still considered played, she can retrieve it.

If another combat is queued after a combat she is part of, she can use her ability between combats to retrieve a card from the previous combat (e.g. she can retrieve a Psyche! she plays)

Her special can only be used once each combat

Black Hand is not a title, it is a trait unrelated to any sect. The trait is not lost if the vampire changes sect.
