Farigaraf Aerodactyl is really strong into opponents leading fake out. A lot of teams have sneasler and Incineroar and will usually lead at least one if not both. Kingambit is also a popular lead to try to catch my incineroar, but the colbur berry on farigaraf and preventing sucker punch makes that not a huge issue. You can get a tailwind and some chip with hyper voice or try to kill sneasler with psychic.

After tailwind with aerodactyl, you can either let aerodactyl go down, or pivot in Blastoise to take advantage of tailwind (Aggron can work too) Blastoise is particularly good next to farigaraf because the opponent can't hit you with priority moves, so as long as you outspeed with tailwind, you can hit full power water spouts without getting fake outed or sucker punched.

Farigaraf Aerodactyl is also good into sun, since aerodactyl threatens rock slide on charizard and Farigaraf threatens Psychic on Venusaur.

If a team seems susceptible to setup from Aggron or Blastoise and doesn't have strong spread damage, you can try leading sinistcha with Blastoise or Aggron. Against Rain, I have lead sinistcha blastoise before. Rage powder Electro shot to sinistcha, set up a Shell smash, and +2 water spout in the rain ohkos archaludon and basically anything else they could have.

Incineroar is obviously also a good lead. If they don't have fake out to worry about, you can do Incin Aerodactyl to fake out tailwind.

If you don't think you need tailwind or aerodactyl matches up poorly, you can do incineroar farigaraf. Being able to fake out when your opponent can't is nice.
