Dispute resulting from deviously tough teasers (5,3,4)
I believe the answer is:
argue the toss
'dispute' is the definition.
(I've seen this before)
'deviously tough teasers' is the wordplay.
'deviously' indicates an anagram (I've seen this in other clues).
'tough'+'teasers'='toughteasers'
'toughteasers' is an anagram of 'ARGUE THE TOSS'.
'resulting from' acts as a link.
(Other definitions for argue the toss that I've seen before include "dispute what's been decided" , "Dispute a decision" .)
