As of 12/18/15, I'm a 1440 on the ubers ladder, which is okay. That is #254 on the ladder.
Mewtwo-Mega-Y @ Mewtwonite Y  
Ability: Pressure  
Shiny: Yes  
EVs: 4 Def / 252 SpA / 252 Spe  
Timid Nature  
- Calm Mind  
- Psystrike  
- Aura Sphere  
- Ice Beam  
Mewtwo provides a strong wallbreaker to my team. It is also a check to Darkrai. It can kind of check Groudon-Primal, Mega Salamence, and Ho-oh.

Scizor @ Choice Band  
Ability: Technician  
Shiny: Yes  
EVs: 248 HP / 252 Atk / 8 SpD  
Brave Nature  
IVs: 0 Spe  
- U-turn  
- Superpower  
- Bullet Punch  
- Pursuit
Choice Band Scizor provides an Arceus and Xerneas check. It also provides Pursuit Trapping and a slow u-turn. It is very strong, but has a huge weakness to Groudon-Primal and Ho-oh

Arceus @ Life Orb  
Ability: Multitype  
Shiny: Yes  
EVs: 252 Atk / 4 Def / 252 Spe  
Adamant Nature  
- Swords Dance  
- Extreme Speed  
- Earthquake  
- Stone Edge  
Arceus is a revenge killer and capable of beating a Groudon-Primal under 50.4% health. However, it is fairly frail, and must set up Swords dance on a Switch.

Xerneas @ Power Herb  
Ability: Fairy Aura  
Shiny: Yes  
EVs: 184 HP / 28 Def / 252 SpA / 44 Spe  
Modest Nature  
- Geomancy  
- Moonblast  
- Focus Blast  
- Aromatherapy  
Xerneas is a late-game sweeper that can leave a trail of dust in it's wake. However, with Groudon-Primal, Ho-oh, Scizor, and Lucario-Mega all viable in Ubers, it can be checked fairly easily. However, it can still do it's job succesfully.

Groudon-Primal @ Red Orb  
Ability: Desolate Land  
Shiny: Yes  
EVs: 176 Atk / 248 SpD / 84 Spe  
Adamant Nature  
- Stealth Rock  
- Dragon Tail  
- Precipice Blades  
- Stone Edge  
Groudon-Primal is a bulky stealth rock setter that is capable of checking the myriad of steel types that bother Xerneas. It can also check The two Magic Bounce users in the tier, Sableye-Mega and Diancie-Mega

Yveltal @ Charti Berry  
Ability: Dark Aura  
Shiny: Yes  
EVs: 248 HP / 252 Def / 8 SpD  
Impish Nature  
- U-turn  
- Foul Play  
- Roost  
- Taunt
Yveltal is a reliable Arceus check and slow U-turn user. It is a great bulky pivot, and can survive very strong physical attacks. However,  If it's berry gets knocked off, it is incapable of checking Extreme Killer Arceus.
