Trickster handy with a card (9,5)
I believe the answer is:
practical joker
'trickster' is the definition.
(synonyms)
'handy with a card' is the wordplay.
I cannot quite see how this works, but
'a' is within the answer.
'card' could be 'joker' (joker is a type of playing card) and 'joker' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for practical joker that I've seen before include "tricks are my speciality" , "one who plays tricks" , "tricks, right up my street" , "Trickster" .)
