Deoxys:In order to get this Pokemon, you must first recruit Articuno, Zapdos, and Moltres and go to their Friend Area "Legendary Island". They will give you a Whirl Stone gaining access to a dungeon called Silver Trench which is ninety-nine floors long. You will fight Lugia there so I suggest bringing high level Pokemon that don't get high damage from mostly Water type attacks. Once Lugia is defeated, he will want to join you. Say yes and you will get another dungeon called "Meteor Cave" the next day. Only twenty fllors long but I suggest only bringing Reviver Seeds, Max Elixirs, and a Friend Bow. You will only use three items so make it worth it. You will fight three forms floors one through nineteen. The last floor has the original. Chances of recruiting him are extremely low.

Jirachi:This involves going to a dungeon called "Wish Cave". First off, you will find Ekans and Medicham at the bush near the bulliten and talk to them. Go to Whiscash's Pond the next day and talk to them. Go there a second time on the third day to find Ekans. On the fourth day, a special mission will be on there. Take it and go to Wish Cave. You can bring a Pokemon with Surf, and you will be at level one. Go to the twentieth floor to rescue Medicham and get a "Wish Stone". Go back again to the ninety-ninth floor to fight Jirachi, if you recruit him, you won't get a wish. If you don't, you can wish for something. It could be money, more strength, a Friend Area, an increase in rank, or a new friend.

Hope this helps you out.
