Very nicely done. You've got a nice sense of humor. But you could develop PuckSilverbreeze's idea into a chapter story. Don't you think a herd dragons arriving at Voldie's lair, crushing his hideout (a Ukranian Ironbelly atop Riddle Manor), toasting his Deaters, and swallowing him whole (sorry for the indigestion, Giver of Life; but that way the Horcruxes don't matter) is a much more satisfying scenario than a series of Archvillians and a bullet to the back of his head (though maybe not as humorous).
An interesting idea for a future story. I've got about 4 ideas on tap for when i finish what I've already got started, I'll make this one #5
