Form my experience playing a similar deck, I always find myself wanting more counterspells. I think you should drop the Unburial Rites to bring up the Mana Leak to four, and Dissipate to at least two. Also, I'd suggest dropping a land for another bomb... maybe another Inferno Titan or a Wurmcoil Engine. Hopefully this helps...-__-
Let me know how the altar works for you though. The deck's not bat atm!

Thanks for the advice! I actually liked the idea of dropping the Unburial Rites, it sped the deck up just a smidge. And i also added in another bomb, that was need because if inferno titan didnt hit and u were on only one vengeance, it was hard to stay in. And Altar of the Lost works amazing, it gives u that little bit of extra reach in the mid to late game that can just burn them away. Also with three color mana base its fantastic.

Since you're already splashing black into this, I'd recommend might be a nice touch.
