I used to run a similar deck pre-M12 using Vampire's Bite, Virulent Swipe and Distortion Strike. UB is probably the better way to go with this, as that gives you access to some removal (including Virulent Wound) as well as much better infectors (Phyrexian Crusader FTW!). You lose out on a lot of pump, but Mutagenic Growth will still get you there, and Undying Evil will help as well.

You'll want Wurmcoil Engine and Solemn Simulacrum. I'd drop Myr Superion in favor of Viridian Emissary. Doomed Traveller, Kessig Cagebreakers and Murder of Crows aren't useful for you, drop them. You'll want some Blade Splicers, some Mayor of Avabrucks maybe, another Acidic Slime, a couple of Archons of Justice and probably a Thrun to help deal with control and aggro. Elesh Norn should be your win condition. You'll want to avoid running anything that isn't a creature, as they won't interact with your pod. Think Twice and Mana Leak are good enough to stay, but the rest should be out. Take a look at my Resilient Pod deck to get an idea of what you might want.
