Serperior has been one of my favorite pokemon of all time, once contrary serperior was released as a legal ability, I just had to use it in competitive play.
Serperior @ Life Orb
Ability: Contrary
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Leaf Storm
- Hidden Power [Fire]
- Dragon Pulse
- Synthesis
The Life Orb will give it extra power to it's already maxed out special attack. Using Leaf Storm will deal lots of damage and raise it's special attack 2 stages. Dragon Pulse is used to sweep dragon types. HP Fire is used to counter ice types. Synthesis is used for healing.
Keldeo @ Leftovers
Ability: Justified
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Calm Mind
- Substitute
- Secret Sword
- Scald
Keldeo is served as a bulky special sweeper and as a counter to fire types. The sub/calm mind combo will ensure that it can sweep without taking too much damage from attacks. Scald and Secret Sword are powerful STAB moves.
Gliscor @ Toxic Orb
Ability: Poison Heal
EVs: 244 HP / 40 Atk / 72 Def / 152 Spe
Impish Nature

- Defog
- Psyshock
Latios is served as a special sweeper and a hazard remover. The life orb will give it a higher special attack for a STAB Draco Meteor and Psyshock to do a lot of damage. Defog removes hazards but also gives a better chance for Leaf Storm and Draco Meteor to hit.

Calm Nature
IVs: 0 Atk
