No, you didn't read the title wrong, according to a CoroCoro issue, various attacks can be combined in double and triple battles, such as the three signature attacks of the Isshu region's starter Pokemon. The three attacks first mentioned which can be combined are:
Oath of Grass, Oath of Fire, and Oath of Water
If Oath of Fire and Oath of Water are combined, it creates a rainbow, boosting the chance of side effects from your team mates attacks. Oath of Grass and Fire combined will create a Fire Storm/Sea of Fire (no, not the Mario 64 level) type effect that works similar to Sandstorm or Hail. And Oath of Grass and Water combined create a wetland, lowering the opponent's speed.
Sounds cool. I wonder what else could be combined? Fire Blast, Hydro Pump and Solarbeam, ala Pokemon Trainer's Final Smash in Brawl? Or, if you were a dick, Explosion, Explosion and Explosion. Okay, that'd be funny, three down and a mini nuke type effect on the Pokemon field with about 750 attack power. Thunder and Hydro Pump? Would that cause higher accuracy, rainy day effect and high damage? Heck, if you ended up combining normal attacks, here's a lethal one... Guillotine and Lock On in the same attack.
In other news, some new official art of a mon known about ages ago was shown:
It was added to the official site at last.
