Dunsparce memes aside, it actually had me thinking about a team that can take advantage of paralyzing the entire enemy team and then utilizing a pokemon that is normally too slow to act as an effective sweeper. This is what I've been thinking about:
Supportive Gyarados
Intimidate
Timid (?) to reduce Confusion dmg a bit
Invest in speed (either max speed, or pick a tier to outspeed) and place the rest in bulk
TWave, Roar, Torment, (Protect?)
Lum berry?
The aim of Gyarados is to paralyze the opponent, then roar to the next opponent and continue to paralyze. Once the entire enemy team is paralyzed or removed, you can Torment the best option and switch to your setup pokemon. You can also obviously swap-stall support with intimidate. I was thinking protect to allow better stall against tormented pokemon but perhaps there is a better move. Also, the only other good TWave + Roar poke I could think of is Zapdos, but the speed isn't too necessary since Roar is low prio anyways and I'd rather have the bulk to take hits, and the speed only matters when trying to TWave the enemy before they make a move. That decision may also come down to ability (Intimidate vs Pressure) and moveset (Gyarados learns torment, while Zapdos can use TBolt to remove opposing water types which may be an issue). With only 3 enemy pokemon it shouldn't be too hard to manage paralyzing all of them, and the combo of Torment + Roar would ruin boosters before they even get a chance to set up. As an added bonus, using Roar to cycle through the enemy team allows you to scout sets before playing around them.
To complement Gyarados, we need a teammate that can A) take TBolt and B) take Rock Slides, meaning a Ground type. We also need a pokemon that can remove opposing ground types who are immune to TWave. The obvious choice here is Swampert.
Swampert
EQ, Surf, Ice Beam, Protect
Leftovers (or leave leftovers for the sweeper)
Protect works well with torment, and Swampert can switch in and remove ground types, STAB rock users, and electric types. Swampert being slow means it can also generally take advantage of paralyzed pokemon.
Finally, we want a pokemon that can effectively sweep, but normally is too slow to do so (our "dunsparce"). In my mind I was thinking of something like a Bulk Up Ursaring. You can switch it in on a paralyzed + tormented pokemon, boost up, and go to town. Even at +2 Ursaring would be devastating, especially if it's attacking before the enemy gets a chance to move. Haven't thought of a moveset but probably something like Double Edge, EQ and RS would work.
###EDIT number 2###
This is merely an experiment on building a bulky/support gyarados/ making use of an good IV magikarp I randomly hatched. The strategy of paralise then roar can be replaced with a more lead focused role of immobilising the first pokemon and replacing the moves listed bellow with moves like: Twave; Toment; Taunt.
DD would work with the below ev's as it give gyara more bulk to set up and can use surf for Rhydon instead of DDing a bunch to KOing with EQ. EQ could damage lanturn and amphoras a bit before being KO'd. HP flying is helpful for heracross, a dangerous pokemon that can set up with SD, bulk up, reversal. HP fly is also useful for pinsir, another OHKO user. I am yet to do calcs but am sure pinsir would be 2HKO'd with minimal attack investment. OHKOing Rhydon with surf is advantages for a lead since it is generally a hard pokemon to deal with if it comes out first, especially without a sturdy user (Rhydon could crit steelix or foretress, skarmory is good but should not be the only reliable OHKO counter). Immunity to fissure and outspeeding sheer cold users helps this lead to secure some kind of move before being KO'd. CPU is likely to use electric moves, so strategies like Green Typhlosions lightnight-rod doubles may work well.
Sassy is also my prefered nature for palace, which is one of the quickest facilities to earn BP.

Cool idea. I randomly hatched a 'wonderfully outstanding' sassy Magikarp a while back and now am finally inspired to make a set for it using that idea. Other natures may be more suitable for higher speed teirs, but I like mixed bulk and offenses. Hope these calcs help.
Gyarados @ Leftovers
Ability: Intimidate
Level: 50
EVs: 226 HP / 40 Def / 236 SpA / 4 SpD / 2 Spe
Sassy Nature
- Thunder Wave
- Roar
- Body Slam
- Surf
• Thunder wave + body slam combo lets Gyarados paralise ground types and electric types (although it loses to electric types).
• Surf + Body slam allow Gyarados to make use of its 125 base attack and SpA investment with a stab will give some power on the SpA side (base 60 isn't all that bad with investment).
• General strategy is to paralise and roar while providing chip damage to pave the way for a sweeper.
• As I'm not running rest I will have a status absorbers, guts users, a sub users.
Calcs:
• 236 SpA Surf OHKO's Horn drill Rhydon, 2HKO's Horn drill Nidoking, Aerodactyl, 91.8% chance to 2HKO Armaldo 1
• 40 Def Gyarados v.s. Intimidated Armaldo 1 3HKO's with Ancient power, intimidated Aerodactyl 3HKO's with rock slide.
• 4 SpD lets Gyarados survive a thunder from Agron and 2HKO it back.
• Gyarados can survive thunderpunches from Metagross 6 and 7, Grumpin 2 and Ludioculo 1, Weezing's thunder and some other weaker electric attacks.
• Sassy nature is not too bad here since roar has negative priority and it has twave.
• A speed stat of 91 outspeeds:
• Hax-Walrien and friends (immune to fissure, outspeeds Horndrill Rhydon)
• Thunderpunch and the leech seed Luduculos,
• Thunderpunch Metagross
• Ampharos, Lanturn (1HKO's Gyarados though)
• Outspeeds a lot of ground and water types, normal types like twave Granbull, walls.
• Gyarados can outspeed the meta when if opposing mon is paralised
