Since the only other black mana symbols in your 75 are for Slaughter Games and E-Plague, I would consider switching out of the black splash as a way of guaranteeing that your dorks make mana. For that matter, you're also running considerably fewer ways to remove a RIP, which makes it that much scarier.
I also see a pretty glaring issue with your Burn matchup given that your only really good cards are artifacts and they'll be bringing in 2-3 Smash to Smithereens. Since you already play 2 Tutors, a single COP Red can swing that matchup enormously.
Those are the only issues I noticed with that list though. I like that your use of Pithing Needle, Revoker, and Spirit of the Labyrinth gives you board targets against miracles that also do work against Sneak and Show ... My Krosan Grips and Council's Judgment are unlikely to pull weight in that matchup, which is why I'm a lot more scared of it than your list probably needs to be (on that note, if there was one thing that convinced me to run black, it's this matchup ... Slaughter Games just seems impossible for them to beat).
