ok, so I have my yveltal in Pokemon y, its name is natures bane, and I'm wondering what I should super train it in. I think speed and sp. attack, but I'm not sure. can I get some help? I just wish to know what I should train it in. the moves are as follows: dark pulse, oblivion wing, shadow claw, and fly.
edit: it has a lax nature, no idea about the ivs. and this is purely an in-game/post game battler. I don't like to go online on older games.
