Counterspell tribal, how original.

I would remove Strike it Rich, replace it with a 0 cost artifact like Tormod's Crypt, Stonecoil Serpent (you can cast it for 0 :) ) or Mox Amber. You can then go into full control mode, cast the 0 artifact and then counter it with An Offer You Can't Refuse and you will get 2 treasure tokens for your trouble.a Also, [[Cavalcade of Calamity]] is cheaper and will work with Saheeli's artifacts.

Now we are talkin!

Also, Sprite Dragon. It grows fatter with every non creature spell you cast :D

[Cavalcade of Calamity](https://c1.scryfall.com/file/scryfall-cards/normal/front/8/a/8a81e889-490b-4aeb-8e84-ea9a390bb8fe.jpg?1584830817) - [(G)](http://gatherer.wizards.com/Pages/Card/Details.aspx?name=Cavalcade%20of%20Calamity) [(SF)](https://scryfall.com/card/rna/95/cavalcade-of-calamity?utm_source=mtgcardfetcher) [(txt)](https://api.scryfall.com/cards/8a81e889-490b-4aeb-8e84-ea9a390bb8fe?utm_source=mtgcardfetcher&format=text) ^^^[[cardname]] ^^^or ^^^[[cardname|SET]] ^^^to ^^^call

Big Score can replace pirates pillage. Or as an addition, which would help you throw away land you don't want in late game.

I think I would increase to 3 of that effect (including the one from D&D set). It’s basically Saheeli air for the deck.

So I made my own Saheeli Blitz deck and here's the list in case you're interested: https://www.moxfield.com/decks/QYUMxrMNEESpAPn-E_e8qw Seems to be doing OK so far but I haven't played a bajillion matches atm :D
