Wizard conjures up ermine jackets (5)
I believe the answer is:
super
'wizard' is the definition.
(both can mean excellent)
'conjures up ermine jackets' is the wordplay.
'jackets' indicates a hidden word (the clue covers or jackets the answer).
'SUPER' is hidden within 'conjures up ermine'.
(Other definitions for super that I've seen before include "Excellent - small-part actor" , "Prefix meaning above or informally great" , "First-rate, top-notch" , "Exceptional" , "Jolly good" .)
