I didn't want to go back to that super muddy thread of mine.
I ended up going with the Mortarion list, hoping to bring a fun, better painted army to the tournament, as competitive as it would be.
I have some mixed feelings, but all in all it was fun, I learned a lot, and the event was very well run.
I lost the debate on using Warp Time, while keeping my Daemon Prince "Death Guard". Long story, I didn't want to push it, I know this was a huge hit to my army but I was fine with that considering my state of mind on entering the tournie. (Let's be honest I was playtesting and getting hosed with Mortarion every game for weeks on end.)
So my list ended up looking like this:
5 Plaguemarines in a Rhino
1 Toilet Cannon dude
1 Pooflinger dude
2 Plagueburst Crawlers
3 x 3 Nurglings.
I will say this much I did a report with pictures on my blog. I go through the games quickly, and highlight them with some various pictures, but I skip a lot to keep it brief. If you want to see the game highlights then here's the LINK

Thanks for everyone chiming in here, and I appreciated bouncing some stuff off of you guys.
