Impressive set of cards and then some! (8)
I believe the answer is:
handsome
'impressive set' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I don't see?
'cards and then some' is the wordplay.
'cards' becomes 'hand' (I've seen this before).
'and then' means one lot of letters go next to another (I've seen this in other clues).
'hand'+'some'='HANDSOME'
'of' is the link.
Can you help me to learn more?
(Other definitions for handsome that I've seen before include "beautiful" , "Attractive, liberal" , "Fit" , "Pleasing in appearance" , "Good-looking or generous" .)
