Victini/Mew in UU is hilarious. V-create ends worlds.
Kyurem isn't. Although the 130 in two attacking stats gives it (some) diversity, its movepool for physical attacks isn't good enough to run anything that's not outrage spam, and steels will lol at that. And it has a TERRIBLE typing. Fighting, Rock, Dragon and even Steel (lolscizor) are used enough that it would go *crunch* in the OU.
That's a pretty good joke, my good friend.
