Pokemon Heart Gold & Soul Silver full trailer

Wow, holy crap. The Eusine battle in Cianwood is complete BS.

 Spoiler

All of his Pokemon have been raised two levels from Crystal, and you're pretty much screwed if you don't have a ground type. Electrode's Thunderbolt will pretty much rape your entire team even if it's resistant to it. If that isn't enough, Drowzee will annoy you with Hypnosis + Dream Eater, or Haunter with Curse.

EDIT: Just beat him.

 Spoiler

Used Quilava as my starter this time. Hypnosis never connected, which was an easy pick off. Electrode only used Thunderbolt once; it was basically 2 turns of wasted moves for it before that. Killed off Haunter with Flaaffy.
