I've got basically 3 teams myself for it, though my strat is a bit different(and inspired by another post on here)
For Aquatic, Call Darkness Nuke team:
GIlnean Raven w/Alpha Strike, Call Darkness, Nocturnal Strike
Brilliant Kaliri w/Quill, Cyclone, Nocturnal Strike
Vampiric Bat w/ Bite, Doesn't Matter, Nocturnal Strike <---- Would prefer a Crow for this slow for extra Call Darkness, but I don't have a rare one yet, so I had to make-do.
Basically CD, NS, swap, NS, swap, NS, swap, and repeat until dead. Usually they die around the second cycle. If the one throws up a Dam, I just delay until he takes it down himself. Can be a bit RNG on the fish because of Whirlpool.
For the Beasts:
Mechanical Gnome(usually with turrets, but I use rocket on Gorespine)
Darkmoon Zepp w/Rocket, Decoy, Explode
Menagerie Custodian w/Overcharge, Shock&Awe, Ion Cannon
Gnome does Rockets or Fist/turret until dead. Swap in Zepp, Decoy, Rocket until they break Decoy, then Explode. 95% of the time he's dead by now. If not, then Ion Cannon should finish it.
For the critters except Nitun:
Zandalari Kneebiter w/Hunting Party, Black Claw, Bloodfang
No, I'm not kidding. I have a P/B breed and he still killed them both solo. Black Claw -> Hunting Party. Usually they'd hit him hard enough to knock him into the Beast "berserk" racial in time for the second wave of Hunting Party, and multiple 500-600 hits finish it. If they ever managed to live past the raptor, I'd be using Flayer Youngling probably for cleanup.
Nitun gets his own special team because of his healing move:
Realisticly, any 3 undead would work, but any with beast attacks like the Vampiric bat are best. The trick is since his ability never actually kills the undead, he never gets a heal. The above Kneebiter trick might work too, but because of Prowl I wouldn't risk it.
