How the clue works
Right, so Cupid at the end is your definition — the little god who pairs up lovers, a proper matchmaker. Now for the build: "one struck" is a nod to MATCH, since that's what you do to a match, you strike it. Then "god" is MAKER, as in the Maker, the creator — stick MATCH and MAKER together and you've got your answer.
