I think a potential lesson from this deck is also that the other lists could only be playing 1 Mountain as well, as normally a big reason to play more basics is to have the option of fetching a painless untapped land when you need it, but Dwarven Mine can already fulfill that role a lot of the time anyways
The real power comes from the ultimate though
