Pokémon Mystery Dungeon: Explorers of Time Tips

how i got my leader and my partner to level 100 easily
first, i keep raising them until they came to lvl. 50+. then i used joy seeds equally among the two. then, i went on missions which rewards me golden seeds then i shared them among the two. in case i ran out of them, i beat bosses in the story (dusknoir, dialga) and the post-endings.(palkia, dusknoir, regis) this is easy. i just showed the tip in case u dont know how to make pokemon lvl. up easily.
