I plan on running both in the 5 color reanimator I'm building. Woodfall Primus is better if you run sac outlets and or if you can cheat him into play like with cards like Flash.
The Mimeoplasm is the only deck I have at the moment, though I need to rebuild it to focus less on the Commander and more on reanimation or just build goodstuff.
I have been playing Damia, Sage of stone to some success but the deck is getting boring fast being good stuff and all. I might switch to The Mimeoplasm as soon as I can get a working build that is decent.
