Question

(This team is built around Xerneas)

Groudon-Primal@Red Orb
Desolate Land
Adamant nature
252 Att/252 HP/4 Spd
-Precipice Blades
-Fire Punch
-Rock Tomb
-Stealth Rock

I've choosen Groudon because it checks many Xerneas-threats like Ho-oh, Genesect, Aegislash, Lucario-mega and Solgaleo. Groudon is by far the best Stealth Rock-setter in the metagame, for it pressures out many Pokemon with its offensive capabilities. Precipice Blades is its best move and hits extremely hard. Fire Punch instead of Lava Plume because I just don't necessarily need a burn. Rock Tomb is better accuracy than Stone Edge or Rock Slide, while still OHKO'ing Ho-oh and highly annoying many Pokemon. Evs and Nature are quite self-explanatory and Red Orb is required to Primal-evolve.

Yveltal@Dread Plate
Dark Aura
Careful Nature
252 HP/252 Spd/4 Att
-Foul Play
-Sucker Punch
-Roost
-Toxic

I've picked Yveltal, because it checks a lot of the metagame, including some Xerneas-threats like Solgaleo, Lugia, Gengar-mega, Groudon, Aegislash and Extreme Killer Arceus. Furthermore, it also provides a handy Ground-, Psychic-, and Prankster-immunity, while also posessing great offensive pressure. Foul Play is to heavily dent Groudon and any attacker that irritates Xerneas, while Sucker Punch is for handy priority, which turns it into a very good revenge-killer. Roost is for recovery and Toxic is to slowly whittle down Dark-resistants while recovering with Roost. I've chosen Dread Plate so that I could fully invest it it's defenses and I've maxed out Special Defense and HP only, because Foul Play takes care of attackers.

Solgaleo@Leftovers
Full Metal Body
Adamant Nature
252 HP/252 Att/4 Spd
-Sunsteel Strike
-Earthquake
-Morning Sun
-Toxic

Solgaleo is here basically to check opposing Geomancy-Xerneas. While not outright OHKO'ing it, Arceus finishes the job for him. There's no reson not to run Sunsteel Strike on Solgaleo and Earthquake is for the Steel-types. Morning Sun is recovery and Toxic is for Pokemon that take less of it's attacks...cough...Kyogre...cough. Evs and Nature are self-explanatory and Leftovers is for extra recovery.

Giratina@Griseous Orb
Levitate
Sassy Nature
252 HP/252 Spd/4 Att
-Will-o-Wisp
-Defog
-Hex
-Dragon Tail

Giratina-Origin is an excellent defogger with quite some offensive capabilities. It also checks almost all the attackers of the metagame, much appreciated by Xerneas. Griseous Orb is there to be its Origin-form. Will-o-Wisp is there to cripple attackers and Hex perfectly pairs up with it. Dragon Tail is for phazing and Defog is logical, while also perfecting the accuracy of Dragon Tail and Will-o-Wisp. EVS and Nature are self-explanatory.

Arceus@Silk Scarf
Multitype
Jolly Nature
252 Spe/252 Att/4 HP
-Sword's Dance
-Extreme Speed
-Earthquake
-Shadow Force

Extreme Killer Arceus along with Geomancy-Xerneas provides infinite offensive pressure on the opposing team. Sword's Dance is there to boost its attack. Extreme Speed is phenomenal. Earthquake and Shadow Force are very strong coverage moves. I've chosen Shadow Force instead of Shadow Claw, because the power difference is just too big. Also Shadow Force catches Aegislash using King's Shield by surprise and breaks through any other protection. Playing mindgames with it is not so easy as it is with Fly, Surf or Dig. Evs and Nature are self-explanatory. Silk Scarf is there to boost Extreme Speed.

Xerneas@Power Herb
Fairy Aura
Modest Nature
252 SAtk/252 HP/4 Def
-Geomancy
-Moonblast
-Hidden Power Ground
-Psyshock

Last but the best, the over-centralizing Geomancy-Xerneas. Geomancy+Power Herb turns Xerneas into a sweeper never seen before. Moonblast deals chunks of damages to anything not resisting it, if not OHKO'ing it. HP Ground is there for Primal Groudon, Solgaleo and other steel-types. Psyshock is for the poison'types and it 2OHKOs Ho-oh after Geomancy. Don't tell me to put Focus Blast/Thunder on it, because I hate those moves. RNG hates me, you know...

I think adamant would be good on Arceus because extreme speed has priority, so it doesn't need speed as much.

---

Jolly is primarily to outspeed other Adamant Arceus, so it's basically anti-meta. Both are fine.

Are you sure that video will help make the team better? If not, then post this as a comment.

Ok, so I've watched your video. Great job on that, I mean how original can mankind be...thank you for that:) It completely made my day great.
So if I properly got what you're saying, you are telling this:
1. Get rid of Rock Tomb
2. Get rid of Dread Plate
3. Get rid of Foul Play
4. Get rid of Solgaleo
So here are my responses:
1. I get your point on this one, however, I'm not using Groudon as a Physical Sweeper. Rather than that, I'm using him as a supporter. I hate low accuracy and Stone Edge makes me want to break my computer sometimes. Although Rock Tomb has a low base power, it OHKOs Ho-oh, and that is everything what Xerneas neads besides Stealth Rock. It also comes with the added bonus of lowering foe's speed, which is surprisingly handy mid-/late-game. That's why, I think Rock Tomb outweighs Stone Edge's advantages, do not hesitate to note it if you do not agree.
2. Here too, I get your point and I'm thinking about removing Dread Plate but not for Leftovers. If anyone could suggest me something? Thank you...
3. Remove Foul Play? Sir, do you know what you are talking about? Could you tell me why?
4. Here's where I do not agree with you at all. You should know that Geomancy-Xerneas is the metagame's centralizing force and everyone needs a reliable counter to it. It is therefore not ridiculous at all to have a Pokemon for the sake of countering Geomancy-Xerneas only.
That was it. Thank you so much for your feedback and for your great video! I'm looking  forward to your response to this comment.
