I am currently using SwagPlay for the suspect ladder and it's actually
very good. However, SwagPlay is a very uncompetitive strategy and can be used in Gen 5 OU and is ridiculously annoying there to. Seriously, last generation, it got an
analysis.
Klefki is easily the staple of all SwagPlay teams. Its unique typing lets you completely monkey around the whole metagame easily switching into things like Scizor and things like Talonflame to completely wreck them with Swagger. However, the confusion itself is not broken and uncompetitive, giving +2 Attack means your opponent will be taking
a lot if it is a physical attacker. Combine this with paralysis, and your opponent will probably RageQuit or lose their pokemon. To be honest, Klefki is really great on swagplay teams: a swagplay team must have it.
Okay, so I want you take a look at Liepard next. One of the few things that come to mind is that it has really fast Foul Play along with Thundurus-I, but I don't really find any use of using it this generation. It's ridiculously frail meaning and has crappy typing meaning that it's easily the easiest to pick off of all SWAG users. However, I have recently discovered a strategy that can even beat Chansey. Yes, Chansey is easily the hardest pokemon to beat on SWAG teams and being able to beat it is a godsend. Say hello to the use of Spite: Spite is a move that drains the PP by 4 of the last move the foe has used. Usually, Chansey will be taking repeated damage from Confusion hax along with Foul Play. If confusion at +4 Atk occurs while you use Foul Play, Chansey will take 25% damage. Two of those? Yup, Chansey will use Softboiled, then you Spite and Softboiled only has 11 PP. Repeat this and Softboiled will have 6 PP then 1PP and from there Chansey cannot do much. This is pretty much the only reason you want to use Liepard due to its ability to easily stall out Roost, Synthesis, and Softboiled from special attackers.
On the Murkrow topic, its typing and being rather bulky with eviolite makes it another good user for swagplay. Sadly, it will either have to give up Substitute or Thunder Wave because Roost is staple on its sets but I prefer Thunder Wave leaving this (for Liepard too) scenario. Murkrow is definetely a good 'mon on swagplay teams.
Thundurus-I is probably the user of swagplay that should always be used because it checks Mega Pinsir which is commonly found on the upper ladder and even a +4 Quick Attack won't do more than you think because like all swagplay users, it can run HP investment. Like Klefki, the lack of a STAB Foul Play is sad, but both of their typings make them definitely worth it.
Sableye is something I don't like on swagplay teams. It's horridly outclassed by Murkrow which has a much better typing and is bulkier thanks to Eviolite (has Roost too so don't say Recover makes it good). Both have STAB Foul Play, so there is really nothing to compare. Don't use Sableye. If you want a spinblocker, then Mega Banette is better. Mega Banette, easily the most oddball swagplay user. It is bulkier than Sableye, but also lacks STAB Foul Play, but the interesting thing about it is mono-ghost typing. This typing is definitely a good draw for using it as it has very few weaknesses meaning that it can Mega Evolve safely because Prankster doesn't take place on the MEvo turn. Pain Split is a staple on it. It completely draws out HP after a couple of Substitutes from the foe while stacking up confusion damage. If you need a spinblocker, just use Mega Banette due to its much better bulk.

How to use the playstyle is a different story. A swagplay team should
never use more than 4 swagplay users or less than 2 swagplay users. Swagplay is a complete waste of a team slot so building around it is your best option. Running to much swagplay is losing its potential. If you want to build a successful swagplay team then
try to use the following.
Easily another staple on swaplay. Its ability to revenge kill dirty threats while sweeping is amazing. If you trace a +6 Attack boost from Mega Heracross for example, you can sweep your opponent clean with Megahorn. Seriously, swagger pairs excellently with Ditto making it easily the most powerful sweeper for swagplay teams. Use this; it's good.
Obviously, you'll have to give up Mega Banette for Mega Absol, but its ability to come in on Chansey and set-up in its face and sweep is great. Magic Bounce is probably the only reason you would want this over Mega Scizor because it completely turns Toxic against Chnasey and makes it easy swag bait late-game on teams that don't want Liepard. Combine this with the fact you can pick off weakened "swagged" threats with Sucker Punch makes it a great addition to swagplay teams.
I guarantee you that swagplay forces the most switches in the metagame than even HO teams! Spikes + SR takes advantage of this while also making games go faster by making things die of confusion damage faster because they already took massive damage from hazards. The part that almost all swag teams have a ghost-type mans that Mega Blastoise and Excadrill won't be ending your hazard fun swag days. Caution of defog however.
Yea, swagplay is easily the most annoying strategy in the current metagame and there is a reason it might be getting the ban hammer: it is
extremely uncompetitive and you win 70% of the time even
without any knowledge of a new metagame
edit: yea, sableye is garbage because it doesnt learn twave
