Sure to use trick (4)

Ross

I believe the answer is:

ruse

'trick' is the definition.
(I've seen this in another clue)

'sure to use' is the wordplay.
'to use' indicates anagramming the letters (I've seen 'using' mean this (the letters used in a different way)).
'sure' with letters rearranged gives 'RUSE'.

(Other definitions for ruse that I've seen before include "Artful ploy" , "Sure its a strange deception" , "Sure to be a plot" , "Subterfuge" , "Deceptive device" .)

I've seen this clue in The Mirror.
