Partner uses trick guard, which has -7 priority, guaranteeing it goes last. Next turn, Shuckle, having the lowest base speed in the game, is moving at the speed of goddamn sound. It'll need Rock Slide or Earthquake to hit both foes at once. Ideally, you'll need Quick Guard or whatever it is to protect Shuckle from priority moves now that it has ten defense.
