I got to say, this tier has quite piqued my curiosity (although, admittedly, I'm late to the party because I didn't know about this tier until it became the OM of the month). I started off building a team based around Flare Boost Accelgor, and the team ultimately ended up looking like this:
- Flare Boost Accelgor
- Unburden Drifblim
- Natural Cure Miltank
- Scrappy Starmie
- Sand Force Aggron
- Sturdy Dugtrio
Then I realized Flare Boost Accelgor just wasn't powerful enough, Drifblim was a detriment to the team due to the omnipresence of Steel-types (I used the standard Acrobatics set), and Aggron is just too slow to be a sweeper (I didn't realize he was Base 50).
So I updated the team, recycling the concept of lead Miltank and a Scrappy Rapid Spinner, and this is what I came up with:
- Magic Bounce Miltank
- Scrappy Hitmonchan
- Justified Espeon
- Iron Fist Lucario
- Sheer Force Accelgor
- Unburden Feraligatr
The team has been successful so far, but this report is not final, since I've only fought two battles with the team (but at least they weren't bad battles). Unburden Feraligatr with a Water Gem is usually what does work on opposing teams. It can revenge kill with Aqua Jet or take out a wall with Waterfall and go to town. Not the best sweeper, but still a potent one. Lucario has some great moves boosted by Iron Fist in Drain Punch and the elemental punches. Slap a Life Orb on it (EDIT: What Life Orb? I run Sash, haha), boost it with Agility, and it can wreck face. Miltank is an amazing lead with Stealth Rock, Body Slam for paralysis, and Seismic Toss to deal reasonable damage, even to Steel-types (and Heal Bell in case I need it). Sheer Force Accelgor is far superior to Flare Boost Accelgor because it doesn't take as much residual damage, doesn't have to sacrifice a moveslot for Protect, and has a more powerful Bug Buzz and Focus Blast.
I've never seen Scrappy Hitmonchan or Justified Espeon at work, but I'm sure they have potential. Hitmonchan can get off a Rapid Spin as long as he can take a hit, and Espeon could potentially take a Dark-type move and Baton Pass it to a physical sweeper. Then again, Dark-type moves aren't all that common in this meta (I can't even name one), and Espeon isn't the bulkiest thing out there.
On another note, I've seen plenty of Normalize+Skill Swap Gengar.
tl;dr - This is a fun tier.
