You know whenever you switch out pokemon they can't attack until the next turn? Well maybe in this game you could choose the attack and attack that turn instead of waiting?
No, absoutely not. For one, that was your battle turn, you used it on switching out, and that's it. if they allowed your idea, then it would be pointless for turn-based battles, like [Super_Fjord] said. It just wouldn't work out that way.
