Create an item that makes one or more currently UU Pokemon competitively viable in the OU metagame.
Switch Top (stat swapper) - UltiMario
Creativity: 6/9
Wave: Sounds like this idea was inspired by moves like Power Swap and Power Trick. Despite that, you put a neat spin on it that open up many, many possibilities.
Creativity: 5/8
Wretched: It is really basic, regardless of the detail that goes into the properties of the move "Switch the highest stat with the lowest stat" is what I guessed everyone would do in the beginning.
Competitive: 6/10
Wave: You covered most of the possibilities in your submission, but here's some more fun ideas: Dragon Dance Latias (130 Atk), Sky Attack Skarmory (140 SpAtk), Metagross (135 Atk, 130 Speed), Specs Haxorus (147 SpAtk) with Draco Meteor, Focus Blast, Surf, Dragon Pulse, and of course, the infamous Choice Specs Gyarados gets a buff. It's definitely tougher to think of possibilities to break OU Pokemon. This item would definitely turn Pokemon upside down.
Competitive: 6/7
Wretched: I like that this move makes SO MANY UU pokemon viable. I don't see it making any OU pokemon too ridiculous, either.
Sexiness: 5/6
Sexiness: 8/10

Average score: 18/25
Elemental Machine (auto-weather) - Bing
Creativity: 6/9
Wave: Beefed up weather Rocks. I like that you encompassed every Pokemon and every weather condition in one item.
Creativity: 7/8
Wretched: I would've never thought to use weather to benefit a pokemon.
Competitive: 5/10
Wave: Weather wars, weather wars everywhere. We've already got Politoed, Ninetales, and Tyranitar. This does make Hail more viable, or at least more flexible, but at the same time it also makes other weathers better as well. I think the most interesting part is the ability to remove weather entirely, but there's little incentive to do that over running 6 Swift Swim or 6 Chlorophyll Pokemon.
Competitive: 2/7
Wretched: The ability to let ANY pokemon control the weather is a bit silly. This item would be a staple on every competitive team, UU and OU alike. The item would end up benefitting pokemon in the OU metagame much more in the long run. I don't like the idea of every match just being a weather battle.

Technical Ring (portable Technician) - asage94
Creativity: 3/9
Wave: See below.
Creativity: 3/8
Wretched: You made an ability an item. Eh.
Competitive: 6/10
Wave: Definitely opens up a lot of possibilities. Purugly can probably revenge kill all kinds of stuff with Fake Out + Quick Attack. Hitmontop is probably broken. Cinccino gets a nice buff. Charge Beam users don't have to worry about possibly needing two Electric-type moves. Acid Spray becomes really scary. Technical Hidden Power 60 in general would be scary, though it isn't a huge boost (70 to 90 base power).
Competitive: 2/7
Wretched: This item would annihilate the metagame of not just UU, but OU and Uber. The thing about moves having low base damage is that they often have better effects, so the idea of making every pokemon in the game's movepool 2x as good scares me.
Sexiness: 3/6
Sexiness: 4/10
3+6+3=12
3+2+4=9
Average score: 10.5/25
Reptition Ring (super Metronome) - Dre.
Creativity: 3/9
Wave: You increased the power of the item Metronome.
Creativity: 4/8
Wretched: It IS an upgraded fury cutter, like you said.
Competitive: 7/10
Wave: Mother of god, mono-attacking bulky Quiver Dance Venomoth would wreck everything. Yanmega might see more use, but Stealth Rock is always a problem. There's a little effect on OU, as well. Haxorus has even more of an incentive to always click Outrage. Jirachi could rely on flinching things to death even more. On late-game sweepers like Terrakion or Lucario, it's basically Moxie.
Competitive: 3/7
Wretched: Every pokemon in the game could make use of this and abuse it.
Sexiness: 4/6
Sexiness: 9/10
Wretched: Still sexy though.
3+7+4=14
4+3+9=16
Average score: 15/25
Levitating Carpet (self-Worry Seed variation) - Xonar
Creativity: 7/9
Wave: I like this idea. It's detrimental to the vast majority of Pokemon, and it's highly beneficial for certain ****ty Pokemon.
Creativity: 5/8
Wretched: If you think about it, the actual effect of the item just nullifies the pokemon's ability, so I can't really say that what an item makes a pokemon NOT DO is the most creative thing in the world. Adding levitate is a good idea, though, because it makes a lot of pokingmens more viable in general (not necessarily UU).
Competitive: 4/10
Wave: Slaking and Regigigas are now basically Uber. Slap a Choice Band or Scarf on them, and they'll basically kill anything that isn't a Ghost with Return, which can 3HKO dedicated physical Steel-type walls. If you opt for Life Orb, you can 2HKO pretty much everything with any combination of Earthquake, Fire Punch, Thunderpunch, Drain Punch, Hammer Arm, and Night Slash. Using Trick with this item is a bit gimmicky, since you might as well use that turn to hit the enemy instead. Addendum: You obviously cannot use a Choice Band, Scarf, or Life Orb if you use this item, disregard.
Competitive: 3/7
Wretched: The only pokemen that this clearly benefits were mentioned in your post, and that is because of their...
SLAKING abilities. The only issue is that this item makes two of these pokemen potentially uber. Slaking and Regigigas have base 670 stats, and now they have no ability to check them at all.
Everything else is gimmicky.
Sexiness: 5/6
Sexiness: 8/10
Wretched: THEY'D BE BALLIN' TO USE THOUGH
7+4+5=17
5+3+8=16
Average score: 16.5/25
Sleeping Cap (Swimming Goggles) - Sold2
Creativity: 5/9
Wave: I'll give you the benefit of the doubt and assume that you didn't copy the hoax that was Swimming Goggles (item that raised Speed and Accuracy of Water-type Pokemon, and put other types of Pokemon to sleep.)
Regardless, using this idea to bump up UU Pokemon is very interesting.
Creativity: 6/8
Wretched: Definitely went to an obscure place of the UU metagame. Sleep talkers.
Competitive: 7/10
Wave: Not sure if it's compatible, but Prankster Murkrow with Sleep Talk and Whirlwind would be silly. That exploit might be banned even from Ubers, since it'd basically force people to run ExtremeSpeed or some other unnecessarily fast priority-user. That aside, it'd be a very interesting tactic to use on walls. Getting off Toxics or Seismic Tosses might be trickier, and healing yourself might be less reliable, but you won't have to worry about Toxic. I'm honestly not sure if it'd be worth the trade-off, which is an interesting dilemma; I'm not sure if Sleep Talk has enough PP to let you do much, since you'd be limited to just 16 moves. You also won't be able to pull off stuff like paralyzing key threats on the switch-in.
Heracross is really scary now. And Hariyama and Conkeldurr as well, to some extent, though only having Fighting for STAB hinder them.
Competitive: 5/7
Wretched: This is probably the first item that takes specific pokemen from UU and makes them competitive in the OU environment. Guts Machamp is so horrifying when he doesn't have to rest, however dynamic punch is then forgotten, and his bulkiness would become null/void with close combat. His only option would be brick break and then his guts boost would seem pointless. This, added to the fact that one of the benefits of sleep talk machamp is rest. The same goes for Hera. However, Slowbro would become much more threatening.

About the scoring: Both judges dole out up to 25 points, and into different categories. Judging criteria and standards are consistent across entries. In the end, two scores of X/25 are averaged.
Congratulations to this week's winner,
UltiMario!
This week's prompt:
Deadline: Sunday, April 1 at 12:00 midnight CDT
In memoriam of an
April Fool's prank that was both devious and
elaborate:
Design a Pokemon with the ability Illusion
Smogon, Bulbapedia. Include its typing, base stats, and a list of competitive moves your Pokemon learns. Source of move (ie tutor, egg move, etc) not required. Specify which tier the Pokemon would be used in (OU will be assumed otherwise).
