I still think it's beyond stupid that drizzle/swift swim is banned. Sandstorm is much more broken.

-Boil Over (Scald)
It's funny I've sweeped an entire team with this once XD. But Boil Over is useful for the burn (hax lol) also so taunt doesn't rape you. Substitute is useful for stalling, his defenses allow him to support a substitute generally for more than one turn. Toxic to widdle down your opponent. And Encore to piss the hell out of spikers and set up pokemon. Tentacruel is your biggest threat but nobody uses him anymore.
