Too slow in several instances. Rooftop storm is worthless, as is call to the grave and zombie apocalypse. I'd even say Endless ranks can be kicked. They are just too slow. Replace them with phyrexian metamorphs and Images, those will do you way more good, especially with undying things. Also, if your opponent has a wurmcoil or something, you can just copy that. Also, you probably want a couple Cavern of Souls at least.
