Schemer reviews its targets (10)
I believe the answer is:
strategist
'schemer' is the definition.
(thesaurus)
'reviews its targets' is the wordplay.
'reviews' indicates anagramming the letters (I've seen 'reviewing' mean this (To re view)).
'its'+'targets'='itstargets'
'itstargets' with letters rearranged gives 'STRATEGIST'.
(Other definitions for strategist that I've seen before include "Expert on the art of planning war" , "Long-term planner" , "general" .)
