Crown without Roaches

So after fiddling around with various crownroach decks on eternal warcry, I found Ladrian's Wurm Crown. I tried it, and extra wurms definitely felt better than clockroaches (turns out even 5 mana 7/7s are pretty good, let alone 4 or 3 mana ones). But the lack of good res effects and BSH inclined me back towards shadow.

After a bit more tinkering, I arrived at this deck. I'd like to have a unit in the market so I could pull it for crown benefit, but I can't really remove Crown of Possibilities, Disjunction (Vision of Austerity wrecks this deck), Sandstorm Scarf (to allow your huge ground worms to set up trades and to shut down scream hard), or Infinite Hourglass to allow attacks and blocks and wreck any stuns. And making sure you have Wurmcalling is pretty useful too.
