Dealer's need (4)
I believe the answer is:
deck
'dealer's need' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for deck that I've seen before include "Floor on board" , "Pack - embellish - ship's floor" , "part of ship" , "Adorn; card pack" , "Pack - floor in boat" .)
