I was looking thru the guide, and I think I have a better approach for Palkia. If we use a Smeargle with an air balloon and the move night shade it is possible to test HP and Speed using 1 pokemon.
This allow to have a fainted sync, and Uxie, Mespirit and Azelf and still have room for the captured pokemon. To do this you want a level 82 smeargle with 0 Speed IV, 16 speed EV and the moves Night Shade and spore (and a recovery move). This will put the smeargle 1 speed point below the boosted 31 iv palkia. So if the Air balloon message comes up before pressure reset. Then use night shade, if the palkia HP goes yellow reset, if not use spore and then another night shade to bring it down to 1 HP.
The only problem with this is that it is only possible for boosted speed natures as smeargle is too fast for neutral.
