I have a deck sort of like this and I coupled blue and black Zendikons with Eradicate as well as Liquimetal Coating with Splinter. Also if you use the zendikon on Griffin Canyon with an Amoeboid Changeling you get an infinitely huge manland. You can see it here.. I feel it's too slow, but maybe it will inspire you.

What about crypt rats? I played a deck like this once and used both pestilence and crypt rats pretty successfully.

They do work in combination, the spell only has to be cast to trigger guttersnipe and nivix cyclops abilities. In order to use the spell with nivmagus you have to cast it and then exile it, so before you exile it everyone else's abilities will trigger. The only downside is not being able to use the spells themselves but they are still nice to have if needed.

I like Lilianna's Caress, I made the swap. The reason I used Stormscape is because I wanted to make Megrim and Warped Devotion a one turn play for 4 mana instead of 6... I may swap it out though, I'll have to play it in the deck first. I am trying to stay away from the discard aspect because I wanted to make a return deck, I just like the warped devotion/liliana's curess combo with it.

I have played a version of this deck and it did great, but the games were a little too close so I swapped out the creatures I was using for some more defense and return ability. If I could just find a good way to get those walls back into play after they die, it would be near-perfect.
