I've been playing Nat Dex recently, and I'm going to add teams that have had success for possible Sample submissions (except for the last one).

MMaw + Sub Kyu Offense
This is an offense built around Mega Mawile. It either mid-game dents or late-game sweeps, either way the team benefits from it. Lando-T acts as the speed control for the team with its Choice Scarf, the Volcarona along with the CM sweeper check with Stone Edge and Punishment, respectively, and the common lead for the team. Ash-Greninja acts a secondary breaker before Mawile comes out, and it also sets up hazards for Mega Mawile; so, it can sweep more easily. Kyurem used to be DD Icicle Spear but was changed to the basic Sub Roost set, as it deals with bulky waters which this team struggles with. Z-Celebrate Victini along with Kyurem usually take care of Rain teams; with Kyurem breaking, and Victini end-game sweeping with Stored Power; Searing Shot, for Ferrothorn; and Focus Blast, for Greninja. Focus Blast was Energy Ball to better deal with annoying Waters but was changed after it couldn't hit Heatran. (Kyuem changed its set at this time too.) Finally, Corviknight is here for a Sub Weavile check as technically Mawile counters it, it is offensive and would take too much damage. Corv also serves as the defogger and Kyurem check.

MGallade Psychic Spam
This is also an offense but built around the Psychic Spam core of Mega Gallade and Tapu Lele. The idea is to have Mega Gallade break or dent the opposing team's Psychic check and then have Tapu Lele clean with nothing to stop it. Due to Mega Gallade pressuring 'mons such as Corviknight and Heatran, I added Volcarona as a Quiver Dance sweeper. I chose Hidden Power Ground over Psychic as, due to the core, I thought I had enough Psychic attacks, and this also lets it take care of Heatran just in case. Tyranitar threatens Flying-type 'mons, sets up Stealth Rock, its own weather, and traps Psychic-types that this team could struggle with otherwise. Ferrothorn and Corviknight are the Fairy checks of the team. Ferrothorn grants hazards in Spikes, Leech Seed chip, and a way to hit Waters while Corviknight grants the team hazard removal and a way to punish U-turn.

CB Hoopa-U VoltTurn Offense
This is a VoltTurn team featuring Banded Hoopa-U. Hoopa-U is good wallbreaker with Choice Band and breaks through many 'mons with its coverage. Rotom-W gives the team hazard control and starts the VoltTurning. Mega Scizor gives the team a late-game sweeper with SD + BP. While somewhat counterintuitive, U-turn on Scizor helps the team out with its pivoting. Lando-T gives the team hazards, a way to punish opposing VoltTurn cores, and some more pivoting. Tapu Koko acts as a secondary, faster breaker that abuses its Electric Terrain to lure in Ground-types, and to fire off powerful STABS in Volt Switch and Thunderbolt. Greninja takes care of the Tapus, Lando-T, Gliscor, and Gastrodon with Gunk Shot, Ice Beam, and Grass Knot, respectively. Grass Knot used to be Spikes but, after the team failed to do even the slightest bit to Gastro, was changed for a better match-up.

BU Buzz + CM MLatias
This is a bulky offense around an interesting 'mon that has won me games outright after taking care of their special attackers. It's Bulk Up Buzzwole! As described above, Buzzwole acts as a win condition if you clear your opponent's offensive, specially oriented 'mons with its Ice + Ground combo. The EV spread on Buzz allows it to outspeed Adamant Tyranitar, and be as bulky as possible while still boosting your Attack stat. It also acts as a Dark resist for Mega Latias. Mega Latias offers another breaker if Buzz fails or after he's taken care of your opponent's special wall or vice versa. Tyranitar traps Psychics that this core struggles with and can't hit too hard at all. Corviknight punishes U-turn and acts as the defogger for this team. Toxapex is the mixed but more special defensively oriented wall. The EV spread on it lets it survive the usual stuff along with outspeeding Reuni expecting 4 Spe (or speed tying with Reuni expecting 8 Spe) Toxapex, so you can Haze before they attack. Scarf Lando-T acts as speed control, pivoting, and a check to Volcarona.

Z-Yawn Toge Memes
As the infamous Sulo has once said, and I quote, "f*ck toge".
So, as you can probably tell by the name above this team is around Z-Yawn Togekiss, which I got the idea from this RMT by RedSkyAtNight. Like it says over there, Z-Yawn Togekiss gives you +1 Speed letting you outspeed lots of threats bar Mega Beedrill (which is trash) and anything faster. The next turn you're free to set up a Nasty Plot and proceed to threaten the other team with infinite flinches for Blissey and to chip stuff it wouldn't OHKO normally. Grimmsnarl sets up Screens here for the hyper offense to work. Mega Charizard X hits the Steels that Toge tends to struggle with a bit and can pave the way for Toge to finish the sweep. The next slot can really be anything, but, because this is for the LOLs and the memes, I added Dual Dance Lando-T with the EdgeQuake combo. And, because it's Lando-T it can never be horrible; only subpar. Kartana takes care of the Water, and the EVs boost its speed with Beast Boost so it can have a proper, full-blown sweep and makes it lose as little health as possible from its Life Orb. Volcarona is a secondary Fire-type sweeper to clear Steels, and, after Mega Charizard X dented their Fire check, an end-game sweeper.
Games w/Z-Yawn Toge:
Me helping Fistwolf test on my alt (vs. Stall)
Me helping Sulo test (vs. Semi-Stall/Fat)

Me helping Sulo test (vs. Semi-Stall/Fat)
After game with Sulo:
is the star of the show here, with Z-Rain Dance letting it boost it's speed and power of water type moves. It's great natural bulk in both stats and typing lets it set up well, possibly getting both a Tail Glow and a Rain Dance in one game. Additionally, it's quite flexible, so you can instead go for Hydro Vortex should that be the best option.
is a great partner. It helps deal with grasses like Tang and Ferro that wall Manaphy hard, and special walls like Blissey.
helps with bulky waters, esp physically defensive ones, deters defog attempts and offers utility in glare.
steal from tf's team dump in the bazaar (it's the same set of mons with some tweaks).
