Set of thirteen cards passed around (6)
I believe the answer is:
spades
'set of thirteen cards' is the definition.
'spades' can be an answer for 'cards' (spade is a kind of card). I am not sure about the 'set of thirteen' bit.
'passed around' is the wordplay.
'around' indicates an anagram.
'passed' anagrammed gives 'SPADES'.
Can you help me to learn more?
(Other definitions for spades that I've seen before include "dark suit" , "Black suit" , "Digging implements" , "Digging tools and card suit" , "They may turn up" .)
