This team I've been using on Doubles in Showdown, I have crafted it myself, and it's getting the job done, but I'd like to see opinions on it nonetheless.
Italics are moves, items, or pokemon in general that I'm iffy on, as they haven't served me as well as other parts of the team.
Some reasoning on the team in general: Originally, I wanted to make an effective Trick Room team using the stars from my singles TR team, but after realizing TR doesn't get priority with Prankster, I quickly swapped it out for other moves, and surprisingly enough, the pokemon are still good and bulky enough to deal a good amount of damage without being destroyed. I'm pretty sure I did at least a bit of team-building well, as just about anything that could be a threat to a teammate is neutered by another teammate. The gimmick for my team is that they all have surprising bulk, while giving up Priority (for the most part, anyways). With great coverage for each-other, priority isn't really needed anyways.
"Meowstic - Male"
"Bluetista, famous for wearing tight jeans and getting gassed"
"Obligatory 'Kotaku evolved' joke"
"Basically Scizor"
"Obligatory 'Maybe it's Maybelline' joke"
"M4risa, famous TF2 player and also great pokemon"
To sum up what I want opinions on the most, I'm not sure how good a Focus Sash is on Meowstic, I can't come up with a good item for Machamp since Assault Vest is on Escavalier, I'm considering putting Protect on just about every pokemon bar Meowstic, and Ampharos is just one big "if".
Funny side note: While making this post and looking through my team's stats, I realized many glaring "problems" with my team, such as Escavalier having 252 Sp. ATK IVs instead of 252 ATK IVs, and Ampharos and Meowstic having no IVs at all. I'm surprised they were as effective even without these.
Thanks for any opinions and info, and remember to keep the criticism constructive, I'd appreciate not getting called "Stupid" or anything like that because of my team or anything.

Calm / Focus Sash / Prankster
IVs: 252 HP \ 252 Sp.Def \ 4 Def
Fake Out | Reflect | Light Screen | Thunder Wave
An obvious choice to start out a good team with, this is the pokemon I first came up with when deciding on making a Doubles team. Prankster serves as great priority for the start of matches, and with Priority Thunder Wave or Fake Out I can effectively cripple just about any threat until I can kill it off. Reflect and Light Screen server as great choices in case everybody on the field is Paralyzed and Fake Out is used up, and it helps toughen up my already bulky team. Fake out was my most recent addition (swapped Flame Orb/Trickster out for it, as usually I couldn't deal burns well enough with it for it to be useful), and with my second partner, I can also make it tough for certain Flying pokemon, such as ZardY.

IVs: 252 Atk \ 252 HP \ 4. Sp.Def
Protect | Dynamic Punch | Stone Edge | Knock Off
While nothing to brag about for sure in any other right, Machamp has surprising synergy with Meowstic as my first two pokemon thrown out. With a unique niche in no-miss moves and good coverage, Machamp can deal with lots of threats relatively well, especially if they've been Paralyzed. Dynamic Punch is a great STAB on Machamp, dealing 150 STAB as well as guaranteeing confusion, meaning even against types that resist it it's still a great move to use. Stone Edge is guaranteed to hit and deals 100 damage, with a high crit ratio and good coverage. Knock Off is a niche move that deals with Psychic threats and also removes pesky stallers. One of my favorite strategies is to Prankster Thunder Wave a Charizard Y while protecting with Machamp, then insta-killing him the next turn with Stone Edge. Never fails to put a smile on my face.

Flamethrower | Surf | Ice Beam | Psychic
The main attraction on my Trick Room singles team, Slowbro was always a great Specially offensive pokemon, having purely awe-inspiring coverage and power to back it up, while not being taking lightly at the same time. He isn't as effective on this team, usually the last pokemon I send out, but he still offers great coverage, 2 powerful STABs, one of which hits everybody, and Ice Beam and Flamethrower for extra coverage. Life Orb is there to push him just over the edge of "Powerful". While I don't plan on getting rid of any of his moves, if Protect served to be more effective on the set, I'd probably get rid of Flamethrower for it.

"Basically Scizor"
Brave / Assault Vest / Overcoat

Drill Run / Iron Head / Megahorn / Poison Jab
Arguably a weaker Scizor, Escavalier is great in that he gets coverage that Scizor couldn't dream of having in Drill Run, as well as being able to effectively run Assault Vest and being immune to Spore and Powder moves. Iron Head is a good STAB with the flinching chance that pops up sometimes, and Megahorn is super powerful, the only real problem it has is missing more than I'd like it to. Poison Jab came from the idea I had at the time that I didn't have an effective Fairy counter (even though that's literally the stupidest thing ever considering what pokemon I put it on), and it has served its dues at times, it isn't nearly as effective. Considering switching it out for something better at some point, still haven't decided.

Dragon Pulse | Discharge | HP Ice | Protect
The most iffy member I have on my team, Ampharos, while more effective for me on the Singles lineup, hasn't served me as well. However, I feel he's still a solid mega for the team, with 2 powerful STABs, one of which is effective against both enemies. Dragon Pulse is really good as a coverage move, and can do very well. HP Ice is there on the off-chance that a Ground type tries to get the upper hand on him, and is more reliable than Focus Miss. Obligatory Protect, because it's just a great Doubles move.

Detect | Ice Beam | Surf | Wish
Vaporeon is probably my favorite wall pokemon ever. Great HP and Defensive stats, and a good Sp. Atk stat to not be set-up bait, it's pretty much the second cornerstone for the team, saving me in a 2 on 1 situation multiple times, and even stalling out Leftovers Suicune. Ice Beam and Surf are great coverage moves, and offer power and protection, Wish in case I have a free turn with it, and of course, Detect over Protect for flare (since they offer no differences from each-other).
