Hey Joey if you made it to this, thanks for taking a look at my team. Here's a list of things to note on this team:
Deoxys-Atk always leads with almost no setbacks. Against opposing Deoxys-A or S always go for the knock off into Espeed. 80% of the time, you can get away with 100% health and if you are lucky no rocks on your side.

If Groudon is the lead, psychoboost is always a good move to go for, anything from 45-60 is usually a sdef set. 65-75 is usually defensive or offensive, in which a second boost just kills.

Again going for attacking moves with deoxys is always a positive turn one unless for some reason you NEED rocks (Lunala, Hooh, Lugia)
If Deoxys-S is the lead against and you need rocks, more than likely it will go for taunt so knock off into espeed is usually the best play.

---------------------------------------
Enough of about the lead, the rest is more or less self explanatory.
Mawile is EV'd to 100% live a focus blast from Geomancy Xerneas and iron head 100% kills
Kyogre's toxic can be used to catch rockpolish groudon on switch. otherwise, Icebeam does the trick.
Arceus is bulky set and can set up on a variety of mons. A big one that people tend to fall for is Groudon. Especially rocks Groudon. The most reoccuring situation is turn 1: Groudon Comes out and rocks or plume psycho boost brings him to around 50 or more. Arceus switches in after Deoxys faints. Typically you risk a chance of burn if hes plume, but it tends to be worth it. Arceus can SD on groudon and espeed most of tier.

Now the most controversial move is probably Flamethrower on Genesect. I actually tend to put explosion on top of that slot since I barely find myself using it. Explosion is also a very good way to deal with a Ho-oh, Kyogre and Groudon that get out of control.

Finally Darkrai is the hit or miss mon. Typically you almost always want to nasty plot with darkrai. However with hypnosis, it makes it so much harder. Yveltal is typically a switch in for darkrai before the hypnosis. after 2 turns of sleep +2 Sludgebomb has a good chance of killing defensive Yveltal. And of course kills xerneas if it switches in at 100%

This is sorta my pride and joy team as it is one of the strongest teams I've ever built but I recently built a decent laddering team beyond this one so I don't mind others knowing the sets. Now this team obviously comes with a big flaw. Rock polish groudon and Lucario have the ability to sweep the whole team if key members of the team are killed. I personally haven't tested it yet. But replacing Darkrai with a roar defensive lugia would round this team very well. guaranteeing that Set up mons dont have a chance to sweep. (unfortunately I would have to run hazard control if I did)

I personally asked for advice on the Rate your team channel but received no comments. So if you have any insights on the team I would like to hear your point of view. You can message me about it through discord. I'm Yellow in your sub list in discord.
