"this set is what i ve choosed, because Haze stops Geomancy boost (Nicely done, fuck wfuu's xerneas), Tentacruel job is set toxic spikes, have a switch in vs Arceus Water, Lugia, Blissey, Xerneas and other mons but these are the most common switch in, Toxic is here because Flying / Levitate mons, like Ho-Oh, Lati@s, etc, Rapid Spin in need of a clean field, very useful.
This set its useful for stop xerneas sweeps and toxic spikes offense."

This is the set that I've chosen, because Haze removes the buffs given from anything, its mainly for geomancy. (Nicely done, f WFUU's Xerneas.) Tentacruel's job within the team is to set up toxic spikes, be a switch in to Arceus-Water, Lugia, Blissey, Xerneas, and other pokemon. Toxic is just Toxic, nuff' said. Rapid Spin helps the team out as it removes the annoying entry hazards that chip away at their health.

"Arceus Ground, the Salamence/ Ho-Oh check and Primal Groudon check too, a thing that i cant understand is why the people says "its bad and the only good set is Sword Dance", for what i ve played and all i will say that is a lie, this set stops Dancer Primal Groudon, let me defog or can be used without defog because i already have a spinner, also checks Poison Types, physical stuff and more, the spread is for Outspeed 90 Base Speed mons, remaining evs on bulk."

Arceus-Ground is my check for Salamence, Ho-oh and Primal Groudon, this set even stops double dancer Primal Groudon. Arceus-Ground can be used with or without defog, as you may think Tentacruel isn't a good enough rapid spinner. The spread is to outspeed 90 base speed pokemons.

"My favorite defensive wall, the best for me to absorb damage, this bird is the ekiller switch in, salamence too, because rocky helmet damages them, Skarmory runs toxic and roost, a great stall combo, also this bird complements the hazzards, because runs spikes and whirlwind, another combo to damage, stop sweeps and toxic spikes poison who enters to field, forgot to say this bird is a toxic absorber."

Skarmory is here to switch into Arceus, and Mega-Salamence, as they both run contact moves which hurt them as Skarmory has Rocky Helmet, which if you don't know, damages the opponents if they use a contact move on the holder.
Skarmory adds even more to set up, with it's layers of spikes, it can whirlwind opponents to forcibly make them take damage.
Toxic and Roost are there because its a great stall combo, it also compliments Gengar-mega as it runs Hex.

"This is necesary on most of Ubers teams, the game is centralized around it (sorry if i wrote bad the word but idk how its the correctly word), Primal Ground is solid as f***, Is my stealth rock user, Precipice Blades hits hard all with a powerful STAB, Rock Slide hits Rayquaza, Ho-Oh, etc. Thunder Wave helps me a lot vs Non Taunt Mewtwo, Mewtwo is one of the biggest threats to the team, specially Mega Mewtwo Y with that good base speed."

Primal-Groudon is here to set up stealth rocks, Precipice Blades hits hard, Rock Slide hits anything that Precipice Blades couldn't hit, and thunder wave helps out since Primal-Groudon is so slow, and helps to take out Mewtwo, one of the biggest threats to the team. Thunder wave also helps out Mega-Gengar as it runs Hex.

"Yeah, wtf is this set. Substitute is helpul agaisnt stall and stuff with twave or status moves, also helps me damage Arceus Life Orb with poison damage and LO Damage, which is useful to erase that and other mon or threat, Hex is needed because is a STAB move and it uses the Tentacruel Toxic Spikes, Protect helps to stall the poison with substitute and Destiny Bond is for stuff that can break the team."

This set is outrageous. Substitute is helpful against crippling status effects against Mega-Gengar, such as thunder wave. since Mega-Gengar takes away the aspect of switching, substitute is amazing here as it makes the toxic death-clock go faster, same with protect. Hex is just a "duh" since you're running toxic spikes. Destiny Bond is there to take out threats to the team.

"This is very important on the offensive of the team because it checks Darkrai, who was a threat, also, Xerneas Scarf kills a lot of things fasts, like Deoxys Attack, Yveltal, Mewtwo-X, Latirwin, etc, Sleep Talk with Moon is for only moonblast when u are sleep, because if u use focus blast or 4 moves, u are risking do another move vs Darkrai Nasty Plot or things like that, helps hitting faster than Support Arceus."

Scarf Xerneas takes out many things, such as Deoxys-Attack, Yveltal, Mewtwo-X, etc, but since this team has a problem with Darkrai, I chose to go with sleep talk Xerneas to take it out quickly, only moonblast as, if you're running 2 other moves, you have a chance Xerneas not attacking with moonblast.
