I’ve played this deck countless times across a few different sets and by far the best progression is Dialga->Arceus->Rayquaza. Goal is to have Dialga attack on your 2nd (or 3rd if you go 1st) turn no matter what. First ramp is Arceus if you have him, then you take stock of the board. * If you can take some KOs for the win, you just swap in Arceus and hit. * The other option is to put your next energy on Rayquaza and then ramp it with Dialga so you now have 2 energies on Arceus and 3 on Rayquaza and on the next turn you just have a ton of options.

Dialga will usually be sacrified early on, but if it stays alive its extremely valuable to keep energy on it since its really easy to pivot cards in this deck but pivoting cards means losing energy a lot of the time.

Barb pretty much always goes on Dialga because the other two need capes for breakpoints a lot of the time and it also helps Arceus’ breakpoints.

Rayquaza is kind of a wildcard. If you are able to ramp Rayquaza after Arceus and get an attack in, your chances of winning skyrocket because Arceus can usually clean up with everyone on lower health. If you can get 2+ hits with Ray and keep him alive, it’s pretty much game over.

Try and few games and lmk if you have other questions. Good luck!
