Introduction
This is a Dual Screens Tapu Koko Hyper Offensive team. It's based around taking advantage of Screens with strong set up sweepers that are supported by a hard hitting breaker and speed control teammates. I peaked at 1750, though I did beat one opponent who was 1930 and a few other higher ladder players, I feel I could maybe take it further with some optimizations. (I didn’t take a screenshot because its not that impressive and I was hoping to get a little higher.)
Teambuilding
+

Tapu Koko is the best Screens setter in the game right now and can form a good VoltTurn core thanks to Volt Switch dealing pretty respectable damage.



I went with my current two favorite setup sweepers, both very hard to stop when boosted and both really appreciate the screens as they have somewhat decent defenses and require more than one boost to really get going.




I added Landorus for a strong U-Turn user, with Knock Off, who doesn’t rely on setup to deal damage, as well as providing a decent physical check with Latias as a special check and an electric immunity that pairs well with Gyarados.





Victini also hits very hard without setup which is nice. It also has U-Turn to form a strong core and good coverage with Bolt Strike, Trick is also very useful to punish set up sweepers and passive walls.






Mimikyu with Red Card phazes out mons who set up on Koko as well as Hawlucha. It also packs a nice secondary speed control method with priority and another decent set of immunities.
Set Descriptions

Tapu Koko @ Light Clay
Ability: Electric Surge
EVs: 248 HP / 44 SpD / 216 Spe
Timid Nature
IVs: 0 Atk
- Reflect
- Light Screen
- Defog
- Volt Switch
Ability: Electric Surge
EVs: 248 HP / 44 SpD / 216 Spe
Timid Nature
IVs: 0 Atk
- Reflect
- Light Screen
- Defog
- Volt Switch
Moves: Tapu Koko is the teams dedicated setter of Light Screen and Reflect. So obviously these two moves are present. I went with Defog over Taunt as I had no where else to fit it without being Choice locked on Landorus which is horrible for momentum and this removes opposing Screens/Aurora Veil and hazards while being less prediction reliant than Taunt. Volt Switch provides momentum, I chose Volt Switch over U-Turn as it can deal significant damage to Toxapex, Tapu Fini and Tornadus-T, while still hitting Greninja and Weavile.
Item/Ability: Light Clay extends Screens to last 8 turns. Electric Terrain prevents Sleep which is nice against Spore Amoongus and Hypnosis on Ninetales which would otherwise force the sacrifice of momentum.
Nature/EVs: EVs and Nature ensure decent bulk behind Screens with full HP, Speed underspeeds opposing Koko for switch initiative, while still outspeeding pre-transformation Greninja, and Weavile to avoid Knock Off the remainder is placed in SpDef.

Landorus-Therian @ Choice Band
Ability: Intimidate
Shiny: Yes
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Earthquake
- Stone Edge
- Knock Off
- U-turn
Ability: Intimidate
Shiny: Yes
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Earthquake
- Stone Edge
- Knock Off
- U-turn
Moves: Its main role is as a breaker however, forming a nice VoltTurn core with Tapu Koko and Victini, Knock Off helps hit or wear down walls like Chansey, Celesteela and Zapdos. Then we have standard EdgeQuake coverage.
Item/Ability: I'm using Choice Band rather than relying on Swords Dance, which frees up a moveslot, prevents this team losing to Unaware walls, provides immediate power and prevents loss of boosts through U-Turn. Intimidate allows Landorus to function as a decent physical check behind Reflect.
Nature/EVs: I find that the damage boost from Adamant is much preferred when multiplied up by Choice Band, and that there aren’t too many significant Speed benchmarks missed, plus with Intimidate and Reflect you are generally in a position to take a hit or two. Standard Max/Max EVs.

Victini @ Choice Scarf
Ability: Victory Star
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- V-create
- U-turn
- Bolt Strike
- Trick
Ability: Victory Star
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- V-create
- U-turn
- Bolt Strike
- Trick
Moves: V-Create has incredible power and is the easiest move to mindlessly click, you still outspeed everything up to Base 100’s after a drop (which you are slower than by 1 point). Bolt Strike hits very hard, particularly in Koko’s Electric Terrain and has a good chance to Paralyse which can be very useful, without drops it is slightly more spammable than V-Create if speed is needed over power. U-Turn allows to finish the VoltTurn core with Tapu Koko and Landorus. Trick can be used to cripple passive walls or set-up sweepers, its generally very useful, in Stall matchups try to absolutely Trick the Scarf to the Unaware wall.
Item/Ability: Choice Scarf outspeeds everything up to Adamant Mega Swampert in Rain and outspeeds every unboosted threat, as well as some common Scarfers like Tapu Lele and Landorus. Victory Star increases the accuracy of V-Create and Bolt Strike, but keep in mind the accuracy still isn’t perfect.
Nature/EVs: Pretty simple Max/Max for the highest possible Speed stat and the rest dumped into Attack.

Gyarados @ Flyinium Z
Ability: Moxie
Shiny: Yes
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Waterfall
- Bounce
- Earthquake
- Dragon Dance
Ability: Moxie
Shiny: Yes
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Waterfall
- Bounce
- Earthquake
- Dragon Dance
Moves: Standard dual STAB with Earthquake to hit Steel-types and Toxapex. Dragon Dance is necessary to hit a good Speed benchmark, two is usually the way to go as you do miss out on Scarf Lele, +1 Zygarde and Mega Alakazam after just one boost, as well as some important KO’s such as OHKO’ing Ferrothorn with a +2 Z-Bounce.
Item/Ability: Flyinium Z gives Gyarados a one-time nuke that can be great to start snowballing and this avoids the set-up turn usually required to hit with a Bounce. Moxie increases Attack after a KO which is great in tandem with the Z-Move to quickly become unwallable, and at +2 Speed often impossible to revenge kill.
Nature/EVs: Again, standard Max/Max, and nature for max speed, which is definitely necessary given Gyarados’ fairly low base Speed.

Latias @ Latiasite
Ability: Levitate
EVs: 252 HP / 4 Def / 252 Spe
Timid Nature
- Calm Mind
- Recover
- Stored Power
- Thunderbolt
Ability: Levitate
EVs: 252 HP / 4 Def / 252 Spe
Timid Nature
- Calm Mind
- Recover
- Stored Power
- Thunderbolt
Moves: Calm Mind is necessary for Latias to deal any significant damage, it also boosts SpDef which makes it a very solid Special check behind Light Screen. Recover allows for longevity and to set up multiple Calm Minds. Stored Power hits 100 base power Psychic STAB move which hits very hard at +2 and the power multiplies up much higher past this, although its starts off at a measly 20 BP. Thunderbolt its for a decent move with more immediate power which can hit notable Pokemon like Celesteela and Dark types.
Item/Ability: The mega stone grants a very necessary boost to Special Attack and Defense, which makes it much easier for Latias to setup and net KO’s. Levitate adds another immunity to its already decent defensive typing.
Nature/EVs: Full Speed EV’s and Timid make best use of Latias’ fancy speed tier, which beats unboosted threats up to and including Kartana, Blacephalon and Keldeo. Full HP is used over SpAtk to ease setting up as you will still hit incredibly hard after boosts, but if you can’t set up Latias is very weak even when invested due to Stored Power’s low BP.

Mimikyu @ Red Card
Ability: Disguise
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Play Rough
- Shadow Claw
- Shadow Sneak
Ability: Disguise
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Swords Dance
- Play Rough
- Shadow Claw
- Shadow Sneak
Moves: Swords Dance is necessary for Mimikyu to hit a workable Attack stat, as it is very underpowered otherwise. Dual STAB and STAB Priority gives Mimikyu very spammable moves thanks to its great offensive typing.
Item/Ability: Red Card helps Mimikyu act as a emergency stop to set-up sweepers who take advantage of the screens setup turns. Disguise means you will not be KO’d by these boosted attackers and provides a guaranteed safe turn to Swords Dance.
Nature/EVs: Standard Max/Max with Jolly to beat everything up to unboosted Kyurem-B, Tapu Lele and Zygarde, all of which it has Super Effective STAB against.

Weaknesses
Protean Greninja can net surprise KO's with coverage and by outspeeding my whole team with Scarf.
Really fat hazard stacking teams can be an issue due to forcing switches and by defogger being pretty unreliable, especially as Victini is vulnerable to all hazards and even Landorus is neutral to Rocks.
Stall is always a difficult matchup, until you can remove the Unaware wall.
Set up sweepers, particularly those with Substitute are trouble if I have already busted by Red Card they can run out of control as this team highly relies on momentum to function.
