Second, i'll explain my battle strategy, by narrating everything that happens when I'm battling:

Turn 8:
Gallade KO's abomasnow with close combat, and loses some hp because of the life orb. Battle ended

Comments after battle:
It was harder than I expected. Maybe it's because I've not played too much lately.


Second battle:

Description:
Be aware of garchomp and armaldo, also, you can get stuck with cradily, making the battle much longer.

I selected(in order):

-gallade
-shaymin
-kyogre
-ho-oh

Turn 1:

Turn 17-19:

Turn 20:

Comments after battle:
Phew, I sometimes get stuck with cradily, but the energy balls and seed flares from shaymin lowered cradily's sp. Defense a lot, making me able to KO cradily with shaymin's last seed flare. Battle finally ends.


Third battle:

Comments after battle:
This can be the easiest battle, or the hardest, it all depends if trick room is used or not. In my opinion, this one was the easiest so far.

Final battle:

Description:
Calm minding is the key! Also remember to keep the weather sunny. (Read this battle only if you used Pokemon diamond to copy your pokemon). Protect groudon, it�ll be more likely to be attacked than kyogre, have kyogre use 6 calm minds.

I selected(in order):

-kyogre
-groudon
-arceus
-ho-oh

Turn 8:
Palkia used special rend on Kyogre, and brings kyogre�s hp down to the red zone. Ho-oh takes out about 1/7 of palkia�s hp using solarbeam, Kyogre uses rest and recovers all of it's hp, and wakes up using it's lum berry.

Turn 9:
Palkia used special rend on Kyogre, and brings kyogre down (it was a critical hit, palkia got lucky). Ho-oh takes palkia�s hp down to half using solarbeam(critical hit), I send out Arceus.

Turn 10:
Palkia used earth power on Arceus, and brings Arceus� hp down to half. Arceus uses judgement(electric) and KO�s mysterial�s palkia. End of the battle.

Comments after battle:
Kyogre would have KOed palkia if palkia�s special rend hadn�t been a critical hit. Kyogre absorbed all of the attacks from foe kyogre, and thanks to the sunny weather, latios� and mewtwo�s thunders missed more often, letting ho-oh finish with latios, mewtwo and kyogre without being attacked at all. That�s my stategy for the last battle. I Hope this helps, and if you want any pokes from my team, follow this link to my Pokemon trading shop here in SuperCheats, and post a reply with the Pokemon you would like to have.
