Mathmech is still crazy strong with just XYZ's. Instead of going for link plays turn 1, you now have the option to go for Redoer which also detaches all your materials for Superfactorial. Or you can hard make Laplacian for a handrip, only recommended if you are cyberse locked (which is often) and when you are able to keep Superfactorial live.
Going second you have an OTK enabler with Utopia Double or you can go for a 4 material ZEUS with the Zoodiacs.
In the side are other options, Flying ''C'' is in there because it was still legal when i played it in the vid below. PK Shade Brigandine is very good when used to make Redoer. And Infra-Flier is another small world bridge that can search Maxx "C" (which Archfiend Eccentric cannot).
Have fun cleaning your opponent's field&hand with Superfactorial :)
