A card from the staff (4)
I believe the answer is:
club
I believe this clue is a double definition.
'a card' is the first definition.
(club is a kind of card)
'the staff' is the second definition.
(thesaurus)
'from' acts as a link.
(Other definitions for club that I've seen before include "Weapon for an association" , "Weapon; playing card" , "sort of sandwich" , "member in black suit > bash" , "Place for dance" .)
