I looked it up, you can get Cresselia, but it doesn't say how. It only says you can get Cresselia at Sharpedo Bluff.
You should beat both stories and get Palkia, Diagla, and Cresselia on your team.
Defeat Darkrai then cresselia will be outside your house talk to her she will join your team.
Home
well you pretty much beat the game. you can also evolve. oh and you get manaphy and cresselia on your team.
Well what do you think? I DON'T KNOW!
The best team is Shinks and Piplup.
no
After when you have beated you have to talk with Cresselia. She wanna join then. hope it helped
Dark Crater be ready he has like 6 other Pokemon helping him and cresselia is low lv
If explorers of time and explorers of sky are the same, I think you can't fight team Raider.
Arceus is not in Explorers of Time or Explorers of Darkness. There is an Arceus statue in Explorers of Sky, but there is no real Arceus that will join your team.
