Forum:Elder Wand Plot Holes

The Elder Wand was said to be the "unbeatable wand." It was also said that if the elder wand is taken from its owner by someone, it becomes rightfully theirs to use. Draco Malfoy was the true owner of the Elder Wand, yet when Harry disarmed Draco, he disarmed Draco's normal wand. Harry never actually took the Elder Wand at all.

Also, there were only a few ways to destroy Horcruxes, and Aveda Kedarva was never mentioned as being one of them. You'd think that Dumbledore would have known that the Killing Curse would take care of a Horcrux. Yet Voldemort used it on Harry, killing his own Horcrux.
