Outside of Winota, how do you like FullFatMayo's Ultra Budget lists?

I've seen FullFatMayo's Winota deck recommended a few times on various reddit posts which led me to finding their other ultra budget lists which are really cheap. Thinking of trying some out for archtypes or commanders that interest me and then upgrading from there. Has anyone had any experience with any of these lists? Obviously I don't expect a $15 to be a complete pubstomper, but am just trying to get a feel for how they hold their own.
