Attractive trap in sorcery (8)
I believe the answer is:
magnetic
'attractive' is the definition.
(synonyms)
'trap in sorcery' is the wordplay.
'trap' becomes 'net' (net is a type of trap).
'in' is an insertion indicator.
'sorcery' becomes 'magic' (I've seen this before).
'net' inserted inside 'magic' is 'MAGNETIC'.
(Other definitions for magnetic that I've seen before include "Very attractive or alluring" , "Drawing" , "attractive result" , "What's attractive" , "Attracting iron or steel" .)
