I don't pretend to be a storm expert, but aren't you making yourself weaker to Workshops by adding in three flusterstorms? With how high percentage of the field being workshops is, it doesn't necessarily feel right to me. Or at least not in my local meta where I faced 50 percent Shops on a Sunday (though one of them was an incredibably odd Shops list).
Your build makes it more resilent but it sounds less explosive.
I do understand cutting Chrome Mox. I haven't been impressed with the card, really. But it has its moments.
While I understand wanting sensei's divining too, it doesn't always do the same thing as ponder and preordain. But of course that doesn't necessarily make it weaker.
