You probably should play 1 MD Tin-street to blow up problematic artifacts, its pretty much just better than Tinkerer.
Also Im not sure why youre running Mad Auntie, and also Im not sure 4 Weirding 1 Gempalm is right, but a split of them is probably best depending how many slots you have. In your list I would cut a Wort for a Tin-Street, and cut Mad Auntie for another Gempalm, and possibly cut some number of Weirdings for Gempalms, I havnt tested Weirding though so Im not sure how good it is compared to Gempalm.
For your Sb I would do away with the 1-ofs and play something like 4 Therapy, 4 Engineered Explosives, 4 Leyline, 3 Krosan Grip, although Im not sure Leyline is necessary in the meta you described, Crypt or Pyrokinesis may just be better.
Also, does anyone else think running Blood Moon Sb may be a good idea with all the Thresh/Landstill running around?
