Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Of course you don't mention me anywhere when I've beat this team like twice.
This is a pretty nice team though. The only real nitpick I have is that your Durant can potentially have trouble with defensive Moltres, due to it not having one super effective move against it, or even a neutral hit...
I remember playing this team on the Ubers ladder on PO yesterday. Its a solid team, but I think you may want to invest 4 more EVs in attack on Arceus to ensure the OHKO from 100% health.
Otherwise, good team, and I wish you luck. [:
This is a pretty well-built team. It caught my attention with the use of Choice Specs Slowbro, a huge threat I've been using on the PO UU ladder for a while. I suggest Fire Blast > Grass Knot, as you have other things to effectively deal with Swampert and Rhyperior, so Grass Knot will not end up...
