Hax. It doesn't really bother me when I get haxed in Wi-fi battles, because I know there's a human player on the other side and he/she's getting haxed about as much as I do. Against the AI, though, it's a diffeerent story. Sometimes I think that the AI is actually programmed to get favourable hax. It's especially irritating when I'm at a high streak at the Battle Maison and then the AI wins by using some dumb luck-based strategy, like King's Rock, or Lax Icense and then the NPC feels the need to taunt me by saying something on the lines of "I won! That means I'm better than you!".
