Dump green. You don't need it. You have creatures, but you're not an aggro deck. The idea isn't to clear the field, it's to get your people through to continue the cypher fed mill train.
Your win conditions lack focus, like I said. Distracted by green.
Too much redundancy and spread too thin. There are a heap of u/b creatures that are not only on curve, cost wise, but have the effects you're relying on other cards for built in, freeing up space for other stuff.
For example, Artful dodge, which I'm sure you'll want to throw on the Ooze or invisible stalker guy thing, becomes moot when you ditch the ooze but also replace him with something like Deathcult Rogue or a full playset of Tormented Soul. Consider Mind Sculpt as well.
Deathright shaman undermines you some. Consider using Duskmantle Guildmage instead. More bang for your buck.
I actually like the inclusion of Mortus Strider. I found that one of the problems this combo has is lack of recycle. If you come up against removal, it's hard to answer and hard to recover from.
