When Damia, Sage of Stone came out, I added black to my Experiment Kraj deck and used her as my commander. Didn't feel like breaking her, so I switched over to The Mimeoplasm and haven't looked back. Often I'll win without playing him at all, but he'll usually just end up copying something with flying from someone else's graveyard and then beating them to death.
Here's the deck in a spoiler tag because I can't get it to divide after the 50th card:
For those that are interested, here's the link to this deck on deckstats.net, which gives great stats: http://deck.tk/7yIV0IUd
There's a few strategies that aren't apparent at first glace. I'll go over those in a moment, but first I'd like to point out a few of the upgrades I'm already looking at, again in a spoiler because you might not care:
I like the idea of a card that can sit there and warn people that your commander will die if you attack me. Plus, Fauna Shaman just isn't that good in this deck. All my creatures are things I want to play. There's the interaction with my general, sure, but it isn't anything that would win games.
Anyone that's ever had someone pod a Wurm into Sheoldred only to have the Wurm come back again knows how crushing that is. Plus, the Vorapede and Archmage survive this chain. People know to kill my Pod.
I'm mainly just wanting some ideas on how to improve this deck even further. Anything you all can think of would be appreciated.
You didn't miss Necrotic Ooze, it's just a very confusing card to keep up with. There's about six other decks in my group, and we all use the graveyard a lot. That card gets so ambiguous in what it can do late game that it's just not fun to play with.
