I've been playing this quite a bit now and I can say, even though some things have yet to be fixed / updated, this is, in my opinion, one of the most entertaining metas released.
We discovered some major threats in the tier that I would like to point out to you guys.
Here are some pokemon that we noticed to have a lot of potential in this meta:
Octillery might become a massive threat in Trick Room if you know how to use it. With Moody it get +2 Special Attack and -2 Speed, every turn I might add. Making it ideal for Trick Room. And with such an amazing movepool, this thing will mess up your entire team if not prepared. Obviously it requires Trick Room to bring it to its full potential and it's not the bulkiest pokemon in existance, this thing can still rip holes in your team with his movepool and coverage within.
Garchomp, Aerodactyl-Mega, Absol-Mega and Salamence might be the best abusers of Hone Claws. Hone Claws giving them +2 Attack and +1 Special Attack is very useful because the afore mentioned pokemon tend to carry a special move for coverage, in most cases this is Fire Blast. Also, Aerodactly being one of the pokemon that lacks good Flying type STAB moves, defonitely appreciated the small power buff to Aerial Ace. Which now also ignores defense changes.
Durant is obviously extremely powerful and fast to mess up your team. Hustle got an extreme buff and Durant doesn't mind that at all. This little thing has a decent movepool which include strong STABs, great coverage moves and even Baton Pass. On the down side is really frail and thus hard to set up. But nonetheless, this thing is not something to mess around with.
Bisharp, obviously amazing because in Gen 6 Defog got a buff and Bisharp with Defiant likes to abuse it to his favor. And not just that, in Skillmons Defog lowers both defenses by 1 stage. This means Bisharp gets +4 in 1 turn. And with Sucker Punch being bugged at the moment, where as it doesn't matter if they use an attacking move or not and you still get priority on it, this thing rips up teams.
Gengar has been mentioned before, but I didn't want to exclude him. As said before, this thing with a solid speed stat tends to be one of the best abusers of Hypnosis. Focus Blast is 100% accurate now for which you trade a bit of power, this is still the move to run on Gengar. Ghost / Fighting has amazing neutral coverage and there for Gengar is a huge ass threat.
Breloom is also a pretty good pokemon in the Skillmons meta. With Dynamic Punch being 100% accurate and nerfed to 50 base power, Technician Breloom likes to make that 100. (probably should be 75, but I'll let Joim handle that.) This thing now also hits 3 times guaranteed with Bullet Seed, which are 30 base power per hit. And also has access to a Sleep inducing move being Spore.
Zygarde, MASSIVE threat. This pokemon is bulky on both sides, with a solid HP stat and even has access to priority, powerful, pretty much unresisted stabs and Coil. Coil might not sounds like the best move, until you realize it gives you +2 Attack, +1 Defense and +1 Special Attack. Dragon Ground is only resisted by a few things, such as Togekiss. And Zygarde has no trouble getting around those with Stone Edge.
Mega Lopunny is blessed with an amazing ability to go with his typing. High Jump Kick being 100% accurate, STAB and have 0 pokemon being immune to that is rather scary. Further does it have a great movepool which include supporting moves such as Encore, Healing Wish and Heal Bell. It also checks Gengar. Obviously it can't switch in to one, but it outspeed and OHKOs with Frustration / Return.
I encourage all of you people reading this to give this meta a try. I personally do not like the OU tier, but Skillmons made it a lot of fun for me. Hopefully you guys like it as well.
And I think I speak on behalf of everyone when I say; thanks a lot, Joim, for creating this!
