One gets rich as if by magic (9,6)

'one gets rich as if by magic' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'one gets rich as if by magic' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is found in the answer.
'as' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
'magic' could be 'wizard' (synonyms) and 'wizard' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
