I know this pokemon come from the NU but I chose Emboar to surprise the OU for today.
Emboar @ Choice Scarf
Ability:Reckless
Ev:252 Atk, 4Def, 252 Spe
Nature:Jolly
-Flare Blitz
-Superpower
-Wild Charge
-Sucker Punch
I chose Emboar to surprise in Over Used, it can outspeed at least the pokemon that have 100 base stat in speed.Flare Blitz the general STAB little OHKO Volcarona, what it surprised me.Superpower the second STAB that allows OHKO Tyranitar and 50% chance OHKOing Defensif Heatran.Wild Charge can counter the water type, but the only thing about the matchup against Gyarados after being set up it outspeed the choice scarf.Sucker punch is the last useless moveset but it can touch ghost or psychic type like, Gengar, Alakazam, ...
252 Atk Reckless Emboar Flare Blitz vs. 0 HP / 0 Def Volcarona: 322-379 (103.5 - 121.8%) -- guaranteed OHKO
252 Atk Reckless Emboar Flare Blitz vs. 0 HP / 0 Def Magearna: 402-474 (133.5 - 157.4%) -- guaranteed OHKO
252 Atk Reckless Emboar Flare Blitz vs. 252 HP / 132+ Def Celesteela: 356-420 (89.4 - 105.5%) -- 37.5% chance to OHKO
252 Atk Emboar Superpower vs. 0 HP / 0 Def Tyranitar: 696-820 (204.1 - 240.4%) -- guaranteed OHKO

Mega Medicham @ Medichamite
Ability: Pure Power
Ev:252Atk, 4Def, 252Spe
Nature:Jolly
-Fake Out
-High Jump Kick
-Ice Punch
-Zen Headbutt
I took Mega Medicham for that jolly nature and not adamant with Pure Power it can hurt very much. Thank's Fake Out the Priority move it can make a free turn after the flinch.Jump Kick are powerful STAB, allows to give big damage but the damage of recoil can happen if miss it with it is 90% of accuracy.I chose Ice Punch and why not Thunder Punch because it can counter Landoruns-T , Dragonite, ... but what a disadvantage by Electric Surge of Tapu Koko.And Zen Headbutt is another STAB that can flinch to 20%
Tangrowth @ Assault Vest
Ability:Regenerator
Ev:252HP, 28Def, 228SpD
Nature:Sassy
-Giga Drain
-Knock off
-Hidden Power [Fire]
-Earthquake
Tangrowth is a good counter against Keldeo Scarf, for the case of Emboar.
Giga Drain allows to recover HP, and more Regenerator can recover HP once switched.Knock off is very excellent to counter Chansey Eviolite, Hidden Power Fire allows to surprise the Steel Type, and Earthquake can make a maximum of damage against Tapu Koko or surprise Heatran.
Landorus-T @ Rocky Helmet
Ability:Itimidate
Ev:252HP, 216Def, 24SpD, 16 Spe
Nature:Impish
-Stealth Rock
-Earthquake
-Hidden Power [Ice]
-U-Turn
As a Sthealt Rock i chose Landorus-T thank to this very great versatility.U-turn allows to switch once the Stealth Rock is posed.Hidden Power Ice can surprise the Dragon Type like Dragonite, and Salamence who have this double weakness.Earthquake this general STAB wich give max damage pay attention to the Flying-Type they are immune.and U-turn in case of difficulty if there is no possibility.
Celesteela @ Flynium Z
Ability:Beast Boost
Ev:4Def/252SpA/252Spe
Nature:Modest
-Autotomize
-Air Slash
-Fire Blast
-Giga Drain
Thanks to Beast boost Celesteela can win a boost in Sp.At, in addition with Flynium Z (Supersonic Skystrike) allows to hit big damage. Air Slash allows flinch and come on Mega Venusaur or Tangrowth.Giga Drain give back more or less correct HP, and Fire Blast allows OHKOing Ferrothorn or Mega Scizor after the set up of Autotomize.
Zapdos @ Leftovers
Ability:Pressure
EV:248HP, 240Def, 20Spe
Nature:Bold
-Discharge
-Roost
-Heat Wave
-Defog
Zapdos is another pretty good Defoger from me because he can counter Mega Pinsir with Discharge, Heat Wave can burn the opponent with 10% chance, Roost can allow to recover from HP but watch out for Earth Power or Earthquake.Defog remove the Hazards like Stealht Rock, Spike, Toxic, ... in short it's not like Tapu Fini
