One handy face card turning up in every deal? (4-2-3-6)
I believe the answer is:
jack-of-all-trades
'one handy face' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'card turning up in every deal?' is the wordplay.
I cannot quite understand how this works, but
'card' could be 'jack' (type of playing card) and 'jack' is found within the answer.
'every' could be 'all' (similar in meaning) and 'all' is found within the answer.
'deal?' could be 'trade' (synonyms) and 'trade' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for jack-of-all-trades that I've seen is " will he do any job?".)
