Pokémon Mystery Dungeon: Blue Rescue Team Cheats

Make Deoxys join your team without fail - it comes with a whopping HP stat, too.
When you fight Deoxys, make sure you're holding a firend bow & drop a reviver seed, walk down so that Deoxys will pick up the seed, kill him, he'll come back, kill him again, he'll join your team with a whopping 950 HP! Train that stat up to reach the maximum of 999 - Sitrus seeds do the trick!
