Really informative piece of work. But it's also a good example for how misleading stats can be. Your composite list is something I've never actually seen played in this configuration and I probably never will play myself. Its just a mix of the both most common builds: the what you call Probasco build with many Thirsts some alternative artifact kill and artifact utility like pithing needle or explosives on the one hand and the famous meandeck build on the other hand. Without the extra artifacts the Thirsts don't seem to be that sexy with much less fodder to discard as many merchant scrolls seem to be too tutor-heavy in the more card-advantage-orientated Probasco build.
We could now discuss the merrits of the single choices, like for example I – as a typical German

– strongly prefer Scryings over Thirstsl. But I guess, thats not what you wanted to start with this article as being already discussed in many other treads.
