Since there is no metagame yet these are just test sets. As soon as a 5th Gen simulator comes out I'll try this team out. The descriptions wont be long.
Tesshiido@Oran Berry
Relaxed Nature (+Def -Spd)
Steel Thorns
EVs: 236 SP Def/236 HP/36 Def
-Spikes
-Stealth Rock
-Gyro Ball
-Explosion
Tesshiido has excellent defenses which means it can easily set up Stealth Rocks and Spikes. If Tesshiido is about to die Explosion will kill the opponent, and that wraps it up.
Yuniran@Choice Scarf
Timid Nature (+Spd -Atk)
Magic Guard
EVs: 236 Spd/236 SP Atk/36 HP
-Psychic
-Shadow Ball
-Energy Ball/Flash Cannon
-Hidden Power [Fighting]
Due to Yuniran's low speed why not slap a choice scarf on it? Psychic is for the obvious STAB, and shadow ball is for Ghost coverage. Hidden power is for Dark type coverage and Energy ball/Flash Cannon is just to fill the last slot. Since there is no metagame yet this is just a test set.
Monozu@Choice Scarf
Adamant Nature (+Atk -SP Atk)
Hustle
EVs: 20 HP/236 Atk/36 Def/212 Spd
-Outrage
-Crunch
-Fire Fang
-Ice Fang
Very hard to switch into since it packs great overage and powerful STAB attacks.
Outrage and Crunch hit hard, Outrage is for sweeping late game while Crunch does a lot of damage.
Fire Fang hits Steel-types super effectively.
Ice Fang hits Gligar and other Dragons super effectively (without resorting to Outrage).
~Smogon LC Analysis
Duskull@Oran Berry
Bold Nature (+Def -Atk)
Levitate
EVs: 236 Def/236 SP Def/36 HP
-Will-O-Wisp
-Evil Eye
-Ice Beam
-Pain Split
Duskull is basically the wall of this team. Will-O-Wisp is to lower the attack of physical sweepers. After that Evil Eye will do more damage. Ice beam is to kill revenge killers like Diglett and Gligar.
Zorua@Oran Berry
Naive Nature (+Spd -SP Def)
Illusion
EVs: 36 HP/200 SP Atk/240 Spd
-Night Burst
-U-turn
-Trickery
-Incinerate
Zorua can burn oran berries with Incinerate, which puts a lot of pokemon in trouble. Zoura can easily U-turn out and Illusion keeps other pokemon away from it. Night burst is it's most powerful move and Trickery is good too. Zorua's movepool is sadly shallow
With the support of Shikijika's Agility, Zorua can out speed Scarfed Chinchous, In your face shnoogle
Just Joking
but seriously it does out speed scarf chinchous.
Shikijika@Oran Berry
Jolly Nature (+Spd -SP Atk)
Herbivore
EVs: 236 Spd/236 HP/236 Def
-Baton Pass
-Substitute
-Agility
-Aromatherapy
This pokemon is the supporter. She, can heal everyone's status problems and baton pass a sub and speed to Zorua.
