(please excuse my perspective, not only am I a new mtg player, but this is also my first post)
GKHord24, can you walk us through a little bit what your strategy will be playing this deck?
At first glance it seems to be a bit on the slow and growing side. Right?
Are you planning on buying all these cards? Is it strictly theoretical? Do you already have them all? $1800, whew...
I've never played a multicolor deck with such a difference in color ratios. Do they work well?
Though, looks like you've got some of that covered with Verdent Catacombs and
Cavern of Souls.
Is there a particular reason you're keeping a little slice of black in your deck?
Here's some alternatives to your
Abrupt Decay :

impulse, if this were my deck, would be to make it a little simpler. But then again I'm kinda new to this.
