I read this thread and decided to create a new alt to see what I could find. I forfeited loads of battles to get down as low as i could and this is what i found:
Lead Aerodactyl with Stealth Rock, SUPERSONIC, and Toxic. Thing is, supersonic hit Kyogre first turn then got 2 turns of confusion. Also, a Metagross without Earthquake which tried to Bullet Punch my Ferrothorn to death.... and these were both on the same team.
An entire team of lower tier Calm Minders and random starters too - Clefable, Alakazam, Swampert, Meganium, Torterra.... another team which had Gigalith, Ampharos, Mismagius with Energy Ball, a mixed Scizor with Air Slash (which hit a crit on Kyogre first turn), Flash Cannon and X-Scissor, Garchomp with Dragon Rush, Blaziken with Bounce, which made me laugh so hard - you can see it here

Magmortar on a rain team with Kyogre, which he led with against my Kyogre to try to Thunderbolt and Earthquake it to death - and it was holding a Big Root o_O. The weird thing was that the rest of his team was completely Ubers or Ubers viable Pokemon.... but his Rayquaza had Dragon Tail, his Darkrai had Spacial Rend (which didn't even do half to Scarf Palkia), his Blissey tried to Flamethrower Ekiller in the rain, and whatever the item was, it wasn't leftovers...
A complete Ubers team except for... lead Regigigas, which tried to Earthquake and Avalance Kyogre to death, then set up Gravity before dying... thing is, i set up Calm Minds against it...
Haxorus with Focus Blast.
Mixed Arceus-Normal with Judgment and Ground Gem Earthquake...
Mewtwo with Drain Punch....
CHANSEY with Drain Punch... and no item...
But the best had to be Vespiquen with Roost, Substitute and Attack Order, which was in a team that also included Perishtrapping Mismagius, Seismitoed with Grass Knot, and a load of other stuff. I decided to boost to +6 with Kyogre just to see what movesets all these weird pokemon had.
