4 Thorn of Amethyst
3 Pyrokinesis (Still not sure if 3 Mox + 3 Pyro is sustainable, but I guess you're only boarding them against Elves anyway)
3 Surgical Extraction - It's free, it's an instant, and it can win you the game T0 against an all-in deck like TinFins. It's also an incredible asset against decks like Lands and can even be good against OmniTell decks with Intuition. I'm currently running 1 RiP Sb just for Goyf MUs, but you're not very worried about that it seems and you're not running W.
2 Krosan Grip - Let's face it, KGrip is the best G sideboard card. It gives you extra game against Omni, Miracles, SFM and black decks running E Plague. If you're playing a G splash you might as well play K Grip.
3 Chalice of the Void - Sandro was advising against running Chalice because of redundancy (too much like Trinisphere). I'm going to respectfully disagree. I think the redundancy makes it better since it compliments 3Ball in combo MUs, but Chalice is incredibly strong on its own outside of combo games. First off, T1 Chalice @ 1 or 0 and T2 Trinisphere will win you the game against most Combo decks. Chalice is not just good against Combo though, it is much much better against Fair decks than other Storm hate. You can easily lock out a RUG, BUG, Infect, RUB Pyromancer or other fair decks with a Chalice @ 1. Splitting the last 3 slots up to have diversified hate is tempting, but hitting that miser's Grafdigger's Cage is unlikely, and you can still wreak havoc with Chalice @ 1 in the matches where you might bring in Cage. On the flip side, a card like Cage is useful in far fewer MUs than Chalice. Running Cage over Chalice puts a much narrower card in your sideboard that you will not bring in as often, and if you're running it as a singleton you'll be less likely to draw it. Same goes for other 1-ofs. Sandro suggested running Relic too, but I think Surgical Extraction will give you stronger graveyard interactions. And, if you winf up facing nothing but RUG Delver and Pyromancer decks, you can side in Chalice instead of Relic which I think is stronger anyway.
4 Trinisphere
3 Pyrokinesis
3 Surgical Extraction
2 Krosan Grip
3 Chalice of the Void
Anywho, that's what I would run with your list and I think it will get the job done. Let us know your thoughts!
