Cutting cards? No, I shuffled (8)
I believe the answer is:
sardonic
'cutting' is the definition.
(thesaurus)
'cards? no i shuffled' is the wordplay.
'shuffled' indicates an anagram.
'cards'+'no'+'i'='cardsnoi'
'cardsnoi' is an anagram of 'SARDONIC'.
(Other definitions for sardonic that I've seen before include "Heartless and bitter" , "Humorous in grim way - seems so rancid" , "Scornfully mocking" , "sneering" , "Cynical -- so rancid (anag)" .)
