Trapper in wonderful drawing (8)
I believe the answer is:
magnetic
'drawing' is the definition.
(I've seen this before)
'trapper in wonderful' is the wordplay.
'trapper' becomes 'net' (something which traps).
'in' means one lot of letters goes inside another.
'wonderful' becomes 'magic' (I've seen this before).
'net' going into 'magic' is 'MAGNETIC'.
(Other definitions for magnetic that I've seen before include "Very attractive or alluring" , "attractive result" , "Having the power to attract" , "Attracting iron or steel" , "Able to attract metal, or charismatic" .)
