As an arceus player myself, I say it really comes down to the skill of the two people playing, I play high level decks all the time, Im based out of southern california one of the biggest tournament turnout areas, and in my local metagame alone there;s luxchomp, dialgachomp, vilegar, kinggar sablelock, donphan, the best of the best; and some of the things i've noticed are:
1. By no means is it a horrible deck like the rikko145 dialgachomp fangirl claims it is.
2. On the other hand his claim isn't totally wrong trainer lock totally wrecks arceus be it vilegar or dialgachomp the fact of the matter is that without uxie arceus uses trainers to speed through its deck with 4 pokedex and 4 beggining door and so on.
3. It CAN and it HAS beaten some of the metagame decks such as the aforementioned dialgachomp and luxchomp and yes in testing the easiest ways to win this match up is by either sniping the benched garchomp or leveling up the normal arceus and attack garchomp for weakness also fire arceus can oneshot dialga lv x even when it has 4 special metals, this is made specially easy by running switches and warp points in the deck.
4. Speed wise its lacking but it is made up for by running lots of draw power 4 Proffesor Oak's New Theory, Some Copy Cat's, and Some looker's Investigation for disruption
5. Lastly Arceus decks arent as reliant on ripple swell as you might think between rainbow and double colorless a lone arceus can use any attack the player thinks is right for the situation
6. It's early game is slow and easily disruptable by taking out a key arceus that is needed for said match up
7. It's mid-late game is really sturdy by using many different attacks and type advantage to find outs to situations
8. Even with all that said its a good deck but is it a tier 1 deck? No. Tier 2? Yes, and its the surprise factor that is most likely is giving it its wins at battle roads, people simply arent expecting it.
Hope this helps clear things up
I was gonna post my list but this is already a long post lol!
