I haven’t played that game for a while and I don’t know what level he is, but I do know that I didn’t train extra to beat him and that the best team I ever had against him was me: totodile partner: pikachu. My partner did a good deal of damage to him, but basically you just need to keep your health up and keep throwing sleep seeds and stuff like that at him, and while he’s sleeping don’t stop attacking because when he wakes up he’s normally going to hit you pretty good, but just make sure you keep him asleep at least 75% of the time and you should be fine. But then again if you have a bad team against his type you’re out of luck.
