The last time I brewed something, the deck looked a lot like the Legecy Sneak Attack deck with Animate Dead. I had 4 Griselbrand and I played around with value creatures like Thought-Knot Seer, Reality Smasher, Stormbreath Dragon and Hellkite Overlord.
I never found a good combination of creatures. My biggest challenge was figuring out the balance of speed and defense. It's like playing Storm, how much discard and counter magic do you need versus acceleration.
