make sure to get a Fire type.... Fire types are Very useful Early game... and also get a Geodude evolve it all te way to Golem Earthquake it ALL!!! hahahaha this is my tip for you for Arceus.... Get a Magnemite with sturdy and Thunderwave and get someone with Destiny bond.... Magnemite spam thunderwave... until it will die,,, then switch to Destiny bond user... and *Poof* dead Arceus..
