A trophy I had, being a divine archer! (5)
I believe the answer is:
cupid
'a divine archer' is the definition.
'cupid' can be an answer for 'archer' (I've seen this before). I'm not sure about the 'a divine' bit.
'a trophy i had' is the wordplay.
'a trophy' becomes 'cup' (cup is a kind of trophy).
'i had' becomes 'id' (I'd).
'cup'+'id'='CUPID'
'being' is the link.
Can you help me to learn more?
(Other definitions for cupid that I've seen before include "heathen god" , "Boy with wings, bow, arrow" , "Roman Eros" , "Love-god" , "boy carrying offensive weapon" .)
