Easy 50 win streak for Battle Tree in Pokemon Sun and Moon

In Battle Tree, if you are looking to get a streak, you want a reliable strategy. This involves things like 100% accuracy moves. It's just not worth using lower accuracy moves as this will kill a streak. You also want a strategy that isn't too dependent on your opponents. So, here is the optimised team I used to beat Red in Super Singles (50th battle). Once I had this team set up, it worked on the first go. My current win streak is 60 and I have suspended for now. It has been incredibly successful and I wanted to share it. I know there are probably better teams out there, but if you want quick BP, then this may be the way to go.

Without further ado, here is the team:

Greninja 'Meniscus' @ Life Orb
Ability: Protean
Timid Nature
EVs: 252 SpA / 252 Spe / 4 HP
- Dark Pulse
- Ice Beam
- Grass Knot
- Surf

The goal is to use Greninja to wipe out as many Pokemon as possible, using Protean to change types for supereffective/neutral STAB Life-Orb-boosted attacks, while using it defensively for resistances. The moves chosen guarantee Neutral-Effectiveness against 336 and Super-Effectiveness against the remaining 582 Pokemon. If you have a choice between neutral Dark Pulse (80 base power) vs Ice Beam/Surf (90 base power) on what you think will be a 2HKO, choose Dark Pulse. The 20% flinch rate kicks in just enough for Greninja to sweep entire teams. Also Ice Beam > Surf due to the freeze chance, though be careful about Fighting, Rock and Steel moves.
Grass Knot is amazing. I recommend looking up the weights of Pokemon before attacking, so you can get the most of out Grass Knot. It's coverage and damage make this set viable.
For some reason, Protean seems to confuse the AI (due to the type changing) and makes it really easy to sweep teams alone. This guy took out ~35 teams by himself. I generally just use him until he dies, then switch into Dragonite or Dusknoir, depending on what I need done. This will also easily take out the Ferrothorn - Dark Pulse x 1/2 depending on the damage, then finish with the stronger Ice Beam.

Dragonite 'Flex' @ Flyinium Z
Ability: Multiscale
Adamant Nature
EVs: 252 Atk / 252 Spe / 4 HP
- Fly
- Earthquake
- Dragon Dance
- Extreme Speed

Dragonite has Multiscale for defense (generally Stealth Rocks aren't played much in Battle Tree, or Dragonite is in battle before they are played), so he usually comes in at 100% HP. Don't bother with Dragon Dance unless you really need it. Last thing you want is your physical sweeper to be Encore-locked or Taunted, since Dragonite isn't the fastest. Greninja has usually done some damage by this point, so Extreme Speed to finish off fast weakened foes/Earthquake and Fly for slower ones. OHKO the first major threat you see with Z-Fly, then proceed to finish the match with either Fly or Earthquake. Anything you think will remotely give you trouble, use Z-Fly on it. Don't fuck around. If you do get a Dragon Dance up (and I don't recommend leading with it unless you know what the opponent will do, you'll win the match. If say, Dusknoir has burned a physical attacker then dies, you can go for Dragon Dance, as you'll have Multiscale + the opponents reduced attack.
Basically just Z-Fly. Try not to switch Dragonite into attacks. It's not worth it. Leave that to Dusknoir. Keep Multiscale in play for as long as possible.

Dusknoir 'Nightshare' @ Leftovers
Ability: Pressure
Careful Nature
EVs: 252 HP / 148 Def / 110 SpD
- Earthquake
- Will-O-Wisp
- Pain Split
- Shadow Sneak

Dusknoir is a change of pace for this team. He is bulky as hell, allowing him to soak up hits from things like Jolteon and other physical and special sweepers. Even from the likes of Salamence and Lati@s. Being Ghost type, he gets immunity to Normal and Fighting moves. Generally lead with Will-O-Wisp unless you're fighting something with low defences and weak to Earthquake or Shadow Sneak. Shadow Sneak is a must, and Earthquake provides great coverage and damage. I don't usually switch Dusknoir in on attacks as I let Greninja die first. In some cases, if Greninja fails to weaken the foe, I'll switch during an attack.
This Pokemon has saved many matches and actually won two matches for via PP-stalling the opponent (due to Pressure, Leftovers and Pain Split). This thing is hard to kill. Sometimes you can just stall a monster for as long as possible, then switch in Dragonite after Dusknoir is KO'd. 

Extra points to make

This team is fairly well balanced, which is what I was striving for: Greninja as a special sweeper, Dragonite as a physical, bulky sweeper with priority, and Dusknoir for bulky, resistant staller. Dragonite could be Jolly, but he loves Adamant Extreme Speed.

IV spreads:
Greninja - 31 HP, x Atk, 31 Def, 31 SpA, 31 SpD, 31 Spe 

Dragonite - 31 HP, 31 Atk, 31 Def, x SpA, 31 SpD, 31 Spe 

Dusknoir - 31 HP, 31 Atk, 31 Def, 31 SpA, 31 SpD, 31 Spe 

Dusknoir @ Leftovers > Dusclops @ Eviolite. Dusknoir gets more attack, and Leftovers are essential in his stalling tactics here. 

The only Pokemon I had any trouble with was the Scrafty with Protect, Bulk Up and Drain Punch. How I beat it was using Dragon Dance x 5 on his Protect and Bulk Up turns turns, then OHKOing hitting with Extreme Speed.

This team beats Trick Room teams with priority moves (Extreme Speed and Shadow Sneak).

I was considering swapping Dragonite for Salamence for better attack, speed and bulk, but losing a godly priority move like Extreme Speed is just not worth it. It saved my run countless times. Though, Salamence is the strongest Pokemon available in Super Singles Sun and Moon IMHO. The Salamence set is the standard Mega-Salamence one:

Salamence @ Salamencite
Ability: Intimidate / Aerilate
EVs: 252 Atk / 252 Spe / 4 HP
Jolly Nature
- Dragon Dance
- Return/Double-Edge
- Roost

- Earthquake

Return for massive Flying STAB Damage (183.6 base power). I prefer it over Double-Edge (216 base power) as you'd take at least half your health in damage per Double-Edge hit. Battle Tree is all about longevity. Earthquake for coverage. Roost for survival. Honestly you probably won't need Roost much, with Greninja around.


So there it is. Have fun owning Red.
