I don't see the benefit of Kataki in the deck? Stax generally fears or at least respects this card over plays it.
I see you are really pushing trying to abuse Land Tax, you may be a little too all-in with that strategy.
Consider some number of Flagstones of Trokair and Windswept Heath (works well with Crucible)
2-4 Ancient Tomb would speed up dropping lock pieces considerably.
4 Mox Diamond, despite how well it works with Land Tax is probably too many.
Why no off color moxen?
Also Balance is generally great in Stax, but 14 creatures makes Balance much weaker.
Smokestack?
just my 2¢
this is pretty clearly not stax though. You should look at the parfait thread and probably steve's article on that deck.
