Adorn with cards? (4)
I believe the answer is:
deck
I believe this clue is a double definition.
'adorn' is the first definition.
(decking is a kind of adorning)
'cards?' is the second definition.
(I've seen this before)
'with' is the link.
(Other definitions for deck that I've seen before include "fell to floor" , "Floor on board" , "Adorn; pack of cards" , "Set of cards" , "Pack of playing cards on board" .)
