Jack, the rascal (5)

I believe the answer is:

knave

This clue is a double definition.

'jack' is the first definition.
(knave can mean a jack playing card)

'the rascal' is the second definition.
(synonyms)

(Other definitions for knave that I've seen before include "Scoundrel - card" , "cheat of old" , "Villain - jack" , "Rat" , "Jack - rogue" .)

I've seen this clue in the Sydney Morning Herald.
