Setup is pretty obvious:
Lead/GravityEarlySweeper/
GravitySetter/SecondGravitySweeper/
Non-GravityLateGameSweeper/Cleaner
This is, very obviously, a gravity team. Smeargle, my lead, tries to get a free sleep (both replays show him getting ferrothorn (No spore)) before setting down sticky web and gravity. He actually generally survives this process and so I can fodder him in the future. The issue is, he doesn't always get off the field cleanly and dark void seems to get me 2 free turns max. After that, it's my choice of who I can run into. Vs ferrothorn, my best option is Landorus-i with focus blast.
Lando-I carries his own gravity if need be, and it's nice to force flying types to get sticky webbed so I can outspeed just about everything. Focus Blast/EarthPower appeared redundant at first, but my two main targets are Ferrothorn and Blissey here, and hitting every time with focus blast really helps take down the blob, or at least disabling it.
Porygon2, of all the setters I tried, is by far the most reliable. He takes all kinds of damage with no issue, fires back incredible amounts of bolt beam spam (And this isn't the standard boltbeam, it's Blizzard Thunder, packing a major denting power) and can get me some interesting abilities to use. He's my standard pivot, so finding WHEN he comes out is difficult. He comes out multiple times, in between multiple parts of my strategy, and sets gravity. With his bulk, as long as he isn't facing a boltbeam resist, I can expect him to at least get one pokemon broken beyond repair or killed, and then expect another gravity set before he goes down.
Dragonite's set is a special boltbeam coverage that works best after Porygon2 sets. While I didn't bother to mess with rocks, he doesn't seem to mind as long as gravity is putting up some minus speed on the opponent. And with EQ, this thing has coverage to almost every pokemon in the game, taking heatran+Magnezone, both who don't care about boltbeam anyways.
Manaphy is actually a late game sweeper with that set, coming in only after most of my gravity setters are gone and outspeeding things that would normally win (Aka Manectric-mega). With Wacan berry, Manaphy can get a free turn to set up and easily take an electric hit. Generally, manaphy's best switches come after Dragonite dies.
Lastly, my mega and cleaner. Often enough, gravity ends a bit early and I can't manage to get another one set. I'll try and lure a pokemon out that scizor can set up on by foddering off a weaker poke. Scizor, with one SD, is a monster that teams just can't take. If I've got their fliers down, it probably is GG unless I haven't done a good job weakening them previously. The opponent is generally slow enough through sticky web that nothing stops him, and Scizor isn't weak to any priority. It's pretty mindless, really. The top replay kind of shows that.
