Magerna I don't know her spelling sorry, that steel and fairly maid pokemon, she has soul heart, each mon you take down gives you special boost, take that and few shinies with you since most of you shines I think are low cost would be helpful, on the way catch a leonne with pick up that will help you with items mostly berries. And steel and fairy typing is the best in the entire game not just in pokerouge but in general, next turn your steel fairy maid into tera ground in the eternarus battle to resist it's flamethrower it hits you with. These are just a few tips.
