Grixis Deck

[waves6]

I'm a completely inexperienced player looking to get a bit better. I'd like some feedback on a deck I modified from a starter set (I've played for a while but never seriously and bought the grixis starter set for the hell of it). Its done well in the few games I've played, but I've just been playing a sibling with another of my decks because I don't really have anyone to play with. I know its a bit big but I'd still love some feedback, and if you're gonna use any slang/jargon, please keep in mind I might not recognize it as, like I said, I have no experience. Thanks in advance!

Here's the deck.
