I've never tried it, but it is neatly costed, and is very black. I'm going to try out greed in my cube for the card draw, and see if it is too slow, or if it can actually be useful.
I seem to run all of theros and some cards from another set or two in my cube, when I look at it.

I don't know if I'm worse, I ended up in mono black the abyss smokestack nether void control. But at least I enjoyed that, when I didn't forget to use my rishadan port so they could get their moat out.
On my third modo cube for the day, thinking that practice makes perfect and all that, but damn, I don't want to take some of the cards, like moat for example, boring to play with, boring to play against, blargharblarghablarg.
I actually enjoy hunting down the best deals on MKM, looking through what people have that is on my wants, and where I get the best deals for it. I sell my other cards on there too, so I'm kinda forced to use my money there if I don't want to lose money in the conversion to paypal or whatever.
