This for the luck of the draw? (9,6)
I believe the answer is:
horseshoe magnet
'this for the luck' is the definition.
The definition suggests a singular noun which matches the answer.
'the draw?' is the wordplay.
I cannot quite understand how this works, but
'draw?' could be 'magnet' (I've seen this before) and 'magnet' is present in the answer.
The remaining letters 'horseshoe' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Another definition for horseshoe magnet that I've seen is " what's attractive".)
