Hi guys, girls and everything in-between! I must do this. I love Gen 7 too much I couldn’t pass away the opportunity to do something like that.
You know it, Gen 7 OU is where I started being good and it is still my favorite metagame thus far. And now, I want do some Gen 7 Delta Draft! I honestly don’t know what Delta Draft actually mean, but I assume this is regular OU but with Delta Pokémon and Insurgence move in it. So, that’s nice 
This team is a Bulky Offense like I love them. Built in about roughly 5 minutes, I think this can be a good team to start with. The gameplay is simple, aggressive and has a good defensive backup and pivoting options. The team, however, have a nasty shared ground Weakness, so Rockium Z Landorus-T is a hard matchup. Here is the team:

Mega Bisharp
This is the Pokémon I started to build around. It have a good offensive Typing in Dark and Steel. Dark typing allows to nail Mega Alakasam, Jirachi and have a good neutral coverage. Dark type toolbox also mean it have very high power Knock Off and Sucker Punch. Bisharp being one of the best check to New Moon team in my opinion, you have a good way to check them. Iron Head cover the plethora of Fairy Type in the meta like Clefable, non-Scarf Tapu Lele, Tapu Bulu, Mega Delta Medichamp and still do high damage to Mega Latias and Tapu Koko. Earthquake is here for Magearna, which defensive variant can take (although not being really resilient), Mega Stunkfisk and itemless Toxapex. Swords Dance is a good alternative to be even more difficult to handle.
Mega Bisharp can be use ti aggressively defend your hazards before Mega Evolving. It also discourage Landorus-T or other intimidate user to come on it before Mega. After Mega, it can be difficult to handle during late-game thanks to Moxie. Its Knock Off and Iron Head can be difficult to pivot around after a boost and can easily pick up weakened teams with Sucker Punch. Mega Bisharp is better during Mid-Late game.
Tornadus-T
Offensive Tornadus-T is an outstanding pivot and Defogger. I wanted to use Z-Fly instead of the Bulky Rocky Helmet to keep the pressure on, plus, Toxapex is already good enough of an Fighting Switch-In. Supersonic Skystrike based of Hurricane is very powerful, allowing OHKO on many offensive threat and having a suprisingly large neutral coverage on its own. Knock Off removes items for its Switch-In like Tapu Koko. Defog is mandatory for its hazard removing properties and U-Trun help gaining momentum.
Tornadus-T is very straight forward to use. Send in on something it check, then do your things. It is a fantastic defogger that doesn’t take Sticky Web nor Spikes. Use the team preview to see what Supersonic Skystrike should be used on, most of the time on things your team would need, because it can struggle against things like Clefable or Ferrothorn by itself without it.
Toxapex
Hehehe… people says its the embodiment of cancer and they are probably right, but it fulfil an important niche in the team, as it cover a lot of fighting type for Mega Bisharp and form a Rege-Core with Tornadus-T. Toxic Spikes can be used, but it can create situation where you cannot paralyze an Ash-Greninja and makes it harder for your team to handle. Plus, Defog remove your Toxic Spikes.
Extremely straight forward to use. Take hits, scald or toxic, haze if necessary then switch back. Look out, some Tapu Fini and Heatran run trapping move and Taunt just for it. It is probably your main check to Ash-Greninja.
Ferrothorn
Seriously, I use Ferrothorn almost all the time. It is just so good as an hazard setter and as a general check to so much of the game. Leech Seed is your main form of recovery alongside Leftovers. Not very sexy, but still your best option. Thunder Wave paralyze foes so Mega Bisharp can more easily sweep late-game. Stealth Rock is your main way to check the extremely dangerous Volcarona. Lastly, Power Whip is just a good move on its own and can deal decent damages.
Ferrothorn compliment very well Toxapex and Tornadus-T. They both enjoy having a check to Electric types and releive pressure to check Ash-Greninja. Toxa-Thorn is also difficult for many rain team to bypass and with how broken rain is in this generation, its ALWAYS a good thing. Use Stealth Rock against Pokémon you check like Tapu Koko so you can setup them safely.
Delta Chandelure
My little novelty because I never used it before. Delta Chandelure has a near ideal speed tier for a choice scarf user. Fire and Fairy works very well in the Meta, covering Dragon, Steel, Grass, Fighting, Dark and Bug. Fairy Aura boost D.Chandelure’s Moonblast to frightening level, while Fire Blast is just great all around. Don’t forget you are using a 95 Moonblast boosted with STAB and Fairy Aura coming from 389 Special attack. Spoiler, Moonblast become 189,525 (Factoring 1,5x from STAB and 1,33x from Fairy Aura) power and deal big damage. Moonblast become For those who are afraid of missing Fire Blast (no shame, it’s perfectly fine), Flamethrower is a perfectly viable alternative. You get more consistent and get les prone to PP Stall, but loose on power. I could recommend when chaining many games back-to-back. Earth Power is the most effective coverage you can get. It rounds up the coverage to Heatran and Toxapex, while also hitting UFI and Mega Diancie for Supper Effective damages. Trick cripples defensive Pokémon like Chansey or Toxapex and ease the Stall matchup.
Delta Chandelure is your main revenge killer. Because it get +1 with the Choice Scarf, it can outspeed the whole unboosted metagame. Look out, as most boosted Pokémon will outspeed Choice Scarf D.Chandelure, the only notable one being +1 Mega TTar. Non-Scarf Greninja, Tapu Koko, Tornadus-T and Mega Alakasam are your prime targets but Delta Chandelure can cover much more with its 145 base special attack.
Gliscor
Gliscor is your Status Absorber and has high potential against Stall team lacking Unaware. It has a perfect defensive synergy with Toxapex and also prevent your team from lacking reliable enough Electric type switch-in, while also being a good check to Landorus-T lacking Hidden Power Ice. The EV spread differ from the more classic one to help it take hits from Mega Charizard and Mega Mawile while also outspending Hoopa-U, Adamant Landorus-T and Timid Heatran. Poison Heal is one of my personal favorite ability after Magic Bounce, Pixilate and Magic Guard. Since you are searching to be poisoned, you can use Earthquake + Facade, which have a surprisingly nice coverage (I curse you Celesteela and Skarmory!). Facade get to 140 BP after poisoning, that’s almost as strong as STAB Earthquake! Keep in mind, since you don’t have Atk investment, you won’t deal that significant damage when unboosted.
Before Poison Heal is active, avoid Knock Off at all cost! Without its Toxic Orb, Gliscor’s whole strategy fall apart. After that, however, then it becomes way easier to pivot Gliscor around. You can sent it directly on incoming Toxic, Will-o-Wisp or Spore all day due to it already having status.
So, what do you think about it? Any comments?
