Well if these were the teams, Palkia would own groudon, while Groudon would on Dialga. Kyogre really isn't that great so it would lose. And Giratiina would shadow force every time Rayquaza Outraged. So team Giratina is far superior!
Ho-Oh, please don't post in threads if no-one else has for a period of two weeks or more. Usually this will get locked, but seeing as people are posting in it again I'll leave it open.
Palkia can OHKO Kyogre Any time just one spacial rend can Defeat Kyogre
Dialga will have a very difficult time with Groudon seing as it's weakness
Giratina(Whch my rival in Real Life think it sucks) Can Be very strong against Rayquaza
