After recruiting Lugia you will gain access to the Meteor Cave dungeon. Put only three huge apples in your inventory. Choose one Pokemon to enter the dungeon; it must be level 100. Defeat one mirage Deoxys per floor to advance to the next. Get to floor 20 and defeat Deoxys when he is in front of you. Deoxys will join your Rescue Team and you will gain access to the enclosed island friend area.
Mewtwo is at Western Cavern on the 99th floor. You can unlock it by recruiting all the Legendary Pokemon before him including Ho-Oh, Entei, Raikou, Suicune, Zapdos, Articuno, Moltres, Kyogre, and Groudon. Western Cavern is a difficult dungeon, and you will be able to recruit almost all of the fully evolved forms of the nine starting Pokemon. To recruit Mewtwo you must defeat him with only one Pokemon in your team. When you get to floor 98, dismiss two of them and prepare for a battle. Mewtwo has about 900 HP.
Save the game just before you go on a rescue. If you die, immediately turn off the power to your DS. Once you turn it back on, it will be as if it never happened. This is useful when going on long missions like Articuno, Groudon, and Rayquaza. It is very hard to complete the second part of some missions if you lose most of your items.
After you defeat the Mankey Gang in Uproar Forest, Jumpluff will give you one Peeled Chestnut. Give it to the Mankey Gang to pay for construction of your team base. You only need two more Chestnuts from Uproar Forest. You usually cannot find them until Floors 7 or 8. Your Pokemon peels a Chestnut to make it a Peeled Chestnut. Once the construction is complete, your base will look like your Pokemon's head.
Always enter the Buried Relic dungeon with at least two Huge Apples or food items. Otherwise when you get to about floor 50, you will faint from hunger.
After defeating Rayquaza, you can go to a cave next to the Wishcash Pond. Your partner will ask if it can leave you and go to its Friend Area. Select "Yes" and you can enter the cave. Inside, a stone will ask if you want to evolve. You can evolve others by going to their Friend Area and selecting "Become Leader".
Once you complete the game, a pit will appear in Wishcash Pond where evolution can be done, However, you must go alone. Try to go to a dungeon. When your partner asks if you want to make team leaders, say yes and become a leader. You can now go by yourself. Enter the pit and there will be a giant crystal that asks if you want to evolve. Say "Yes" and it will ask for an item. If you give one to it you will have a better chance to evolve. It will then ask again. If you give another item you will have an even better chance. When it thinks you are ready a big beam will appear and you will evolve.
Some Pokemon require the use of items to evolve, such as stones or ribbons. Here are the locations of those items:
