Well, I have PMD blue rescue team, and I have just discovered that this game is so LONG. I mean, it's better that it's longer, but 99 floors? That's quite a bit. These are the legendaries I have in order. The ones a like the most to the ones I like the least.
5. Latios/ Latias
I'm gonig after Deoxys now. He is only 20 floors, but It's hard to find his helpers! You need to kill his helpers before you can get to the next floor. [pitfall traps are useful in this dungeon]
