Hi, since Arceus is a big part of the Ubers metagame, I'm planning on writing an article on how to narrow down and attempt to predict what Arceus forme and potentially which set your opponent has when you see it on team preview. An important thing to note that obviously the guidelines I'm going to be setting will not work all the time, but in general, different Arceus formes work on teams, and by looking at the other Pokemon on Team Preview, you should be able to have a general idea on which Arceus forme it is more likely to be.
