Fate of clubs, behold, all the same (6)
I believe the answer is:
clotho
'fate' is the definition.
(one of the Fates of Greek mythology)
'clubs behold all the same' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'behold' becomes 'lo' ('lo' is an archaic exclamation meaning 'look!').
'all the same' becomes 'tho' (though).
'c'+'lo'+'tho'='CLOTHO'
'of' acts as a link.
(Other definitions for clotho that I've seen before include "female controlling destiny" , "One of the three Fates (she spins!)" , "puff-adder" , "Fate who spun thread of life" , "Greek goddess of fate who spins the thread of life" .)
