The stock set was 3-PW with a 34-degree 7-iron and a 46-degree pitching wedge. Specs below are the men's standard steel-shaft build.

Do the MP-18 MB and MP-18 SC share the same lofts?

Finding a used set
The Mizuno MP-18 MB ran from 2017 to 2019 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
