Maybe next gen. Definitely not this gen... and no, if Smogon or any other group ever bans Drizzle on Kyogre for whatever reason, it doesn't count. This is assuming it gets a dream world ability or something.
Kyogre does not, at present, get a Dream World ability. It's not programmed to be able to do so.
I guess I wasn't clear enough, but by that I meant in a future game.
Everything in life is a battle. Even peace itself is a battle to maintain it.
The very existence of this topic is a clear demonstration of just how little people (including many people on Smogon, who even up to this day still continue to insist that Kyogre is the best PokÚmon in ▄bers) know about the ▄bers metagame (no offense to anyone).
But to answer the topic creator's question, Kyogre lost its title of "Best PokÚmon in ▄ber" on the 18th of July, 2009 (source: http://www.serebii.net/events/dex/493.shtml). Right now, I do think it is the second best PokÚmon in ▄bers, but it is far from the best by a long shot.
Oh, and just for credibility: (21:09:35) ▒Porygon: Your rank in Wifi Ubers is 1/40378 [1679 points / 205 battles]!
And I have decayed a bit. Without decay, I have 1700+ points.
