Start out with Lycanroc and Gigalith. Lycanroc outspeeds Excadrill by a good 30 points with a sandstorm, so all he has to worry about is Bullet Punch, Aqua Jet and maybe an earthquake from my Gigalith. Even then, he can handle one hit thanks to Focus Sash. He Fire Fangs Excadrill, Crunches Metagross and pretty much Rock Slides everything else for a chance at a flinch. Gigalith then Rock Slides again in hopes of taking anything out, unless Lele's out, in which case he Heavy Slams him. Above all, treat Excadrill as the top threat, as he can outspeed everything once Lycanroc is dead. Even if Lycanroc dies, Gigalith is welcome to use Earthquake to take him down if necessary.
Mudsdale probably will switch in from Lycanroc, whether or not he dies as a result of Gigalith. Gigalith's EQ will up his defense by one, plus whoever decides to attack him, turning him into a tank. This pic's a little dated, he has Leftovers now, but whatever. He uses a similar moveset to Gigalith, but with Highhorse power as a single attack, so that way he doesn't have to hurt Gigalith.
As of this point, if Exacadrill isn't killed, I'm screwed. However, if it is, then once Gigalith is down, I send out Vikavolt. Discharge/Earthquake combo, with maybe Rock Slide if Salamence is out. Repeat until someone dies. AS of now, treat Keldeo as top threat, he can take out pretty much all of my team.
After this, I rely on Greninja or Incineroar. Unless Lele is scarfed, T-tar has DDanced or Keldeo is still alive, I send out Greninja for an easy kill. Probably use Mat Block for an extra turn and extra damage form his partner. U turn to something that he can't handle, unless I know he can get out sped, in which case I just normally switch.
Incineroar either uses Fakeout or Flame Charge to get extra speed. He can pretty much out speed most of the team after one go, unless something is up. After that, I use Darkest Lariat constantly.
Beyond that, I have no fuckin' clue. I'm using what I want.
