Comments

Replace Weavile and Blaziken with Yveltal for better stats and Groudon for a bulky stealth rock user. Give Arceus a life orb for more power and 4 HP/252 Atk/252 Spe jolly to outspeed other Arceuses. Give Salamence 252 Atk/4 SpD 252 Spe adamant to take advantage of its stronger physical attack. Replace hyper voice, defog, and roar with dragon dance to raise its stats, double-edge for STAB, and earthquake to cover electric, rock, and steel. Give Ho-Oh 252 Atk/4 Def/252 Spe adamant to outspeed more stuff. Replace sleep talk with toxic to cripple bulky opponents. Give Giratina a griseous orb for better offensive stats and spikes immunity and 4 HP/252 Def/252 SpA modest for more power. Replace rest with hex to take advantage of toxic.

You know sumwun, this team's point is to be unpredictable.

Plus first No one Expects Hyper Voice and Defog From Mega Salamence next defog on mega Salamence can Basically Counter Stealth rock users like Dialga and Primal Groudon then weaviles Moveset is for An Anti Suicide lead and Low kick For Dealing with heavy Pokemon Since There tons like Dialga and arceus Steel. Next Taunt Stop Setup Mons  Like Other Mega Salamences and Normal Arceus.

You asked for advice and you got it. I don't think you gain anything from dismissing people as not having understood the 'point' of the team.
I have not played Ubers in years and I don't claim to have any knowledge of the meta, but I'd be careful mistaking 'unpredictable' with 'subpar'.

Just because a team is unpredictable doesn't mean it's good. For example, if someone was expecting double-edge from Salamence, he/she/it'll switch to a bulky flying resist like Magearna. Then, your Salamence uses hyper voice, and it does just as little damage as it would have done if it used double-edge. Unpredictability is only good when you can actually take advantage of mis-predictions. Also, you should still replace Weavile with Yveltal. Yveltal uses taunt just like Weavile does, and its focus blast is usually stronger than Weavile's low kick. Also also, can you please call me "sumwun" and not "Sumwun"? Thanks.
