I don't know why wouldn't want to make a deck like that. Mimeoplasm is a great general in arguably the strongest color combination, so you can do pretty much whatever you want with him. These ideas sound a lot like one of my friends decks, he used self mill and reanimation to great effect.
If you still want a good instant kill option, buried alive looking for wonder, deaths shadow, and gaea's revenge is pretty nasty. Cast your general and you end up with a evasive 21 power general with haste that's almost totally untargetable
