“Slow-paced”: Arab’s barbed comment during deal (10)

'slow-paced arab's barbed comment during deal' is the definition.
I can't judge whether this definition defines the answer.

'arab's barbed comment during deal' is the wordplay.
I cannot quite see how this works, but
'comment' could be 'dig' (dig is a kind of comment) and 'dig' is found in the answer.
'arab' could be 'ar' (abbreviation in Chambers) and 'ar' is present in the answer.
'deal' could be 'trade' (synonyms) and 'trade' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
