I need someon to rate my team all at lvl. 100 1. Entei with eruption, fire..

If it is legitimate, then 7/10. If it is hacked then 2/10. (Those are some impressive Pokemon IF they are legitimate, and if they are hacks then you could have hacked better).

Your Pokemon don't have too good of movesets.
Entei knows two fire type moves, and Roar doesn't make sense because there aren't any other moves that Roar can abuse (Thunder Wave, Spikes, Toxic Spikes, Stealth Rock...Entei doesn't need to know one of these, but someone should).
Arceus knows two dragon moves, and unless you have it holding a good plate, it has an odd type spread. I would suggest using something to take out Steel-types.
Castform seems very out of place. It is the weakest, both defensively and offensively. It isn't a bad Pokemon, it is just very inferior compared to the rest.
Your team has two water types, which works with the rain from Castform, but is odd.

Overall criticism: Movesets are not where they could be.

My answer is maybe you should switch empoleon (he sucks against earthquake)for like a feraligatr. Wen I was battling one I had like a level 40 something tangela and he just used waterfall I died in one hit even though tangela is grass
