very good read
Also in my testing the goblin tinkerer/vandal has not been the greatest whatsoever. I would much rather have a prospector or some other resourceful goblin in that slot. Once you get them active, more than likely, the acceleration of the opposing artifacts has been used and its not going to matter. In these early turns (2-3) you should be trying to set up to combo out on 4, or go aggro on 4-5.
I am torn on the issue of Wheel. It's something i am going to have to test, but it just seems it will be something that would be sideboarded out, or it would be a "win more" card.
