Alright Gemini, good work so far.

Start this round with a Nasty Plot to beef up your special attack, then let Leviathan have it with a double dose of electricity, in the form of a pair of Shock Waves!

Once again, be ready to Snatch anything you can Snatch (except Rest, if he decides to do that, Taunt him) or Magic Coat anything you can reflect back. If he triggers any of your subs, make sure your next move is Nasty Plot if you didn't get it off, or Shock Wave if you did. Leviathan is going to soon realize just how tough you can be, Gemini!
