Perfect card distributor's job description? (5)
I believe the answer is:
ideal
This clue is a double definition.
'perfect' is the first definition.
(similar in meaning)
'card distributor's job description?' is the second definition.
(a dealer might say 'I deal')
(Other definitions for ideal that I've seen before include "Exemplary" , "Model of excellance" , "Ailed (anag)" , "faultless" , "Model of excellence (5)." .)
