Last night I ended up winning a 9 player free for all, with my Blue/Black zombie mill deck. When it was down to just myself and one other player, I had 15 2/2 zombie tokens (made earlier by Undead Alchemist) and a 20/20 Wight of Precinct Six. Plus the Nightveil Spectre. It was a serious amount of fun.
I ended up staying alive, as most people started targeting each other with extreme prejudice. So people were being picked off pretty quickly and early on.
