To get magmarizer you need to catch a wild Magby. Some have them holding it as an item. Or if you already have a Magby, get a Pokemon that knows snatch, confront a wild one and natch it away. You can find Magbys in mount stark with a copy of LeafGreen inserted during the day, if you do not already have one.
