I'm seeing some red in your mana distribution, wouldn't prefer to switch that
cinder glade with a
jungle hollow or some other dual land that gives you B/G? It'll make your mana fixing more consistent. Also like a recommended to another person, if you add
shadows of the past to your deck you can scry repeatedly as creatures die and ALWAYS have a high drop creature on top of your deck when you need it. It'd be a good way to speed through your deck since the colors you're playing are almost made for aggro.
