I was fighting against Koga's Swalot. It killed my Meganium with Sludge Bomb. Okay, fine. It's a poison move after all. But the problem was, all I had left was a level 1 Skarmory. So yeah, I sent it out. Fortunately, Koga had no Sludge Bombs left, it used all of it against Meganium. Unfortunately, it turned into a half hour stall because Swalot's only attack was Sludge Bomb. Pain Split, my Skarmory's fine, his Swalot drops down to something like 20 hp. Recovers thanks to uhh...leftovers I think. Pain Split, Yawn, Amnesia... half hour later, Struggle. YAY!!! Finally out of there!
The other time. Red's Pikachu uses Volt Tackle! It's a critical hit! It's not very effective. Meganium fainted. I'll be back for you and your little Pikachu....
