despite my initial hesitance, simple whiscash seems to be my favorite choice for this slate. offensive ddancer that can be pretty hard to stop once it sets up, doesnt take up a mega slot, and has a pretty solid defensive typing that helps it set up. its main selling point over feraligatr or gyarados, the other two non-mega water-type dragon-dancers (thats a mouthful), are its ability to set up on electric-types, reliable secondary STAB (thats not bounce, lol) , and ability to boost faster. however, whiscash' smain pretty much exclusively suits the role of late-game cleaner, whereas gatr can wallbreak early- to mid-game before setting up, and gyarados can pivot to check stuff like landog or excadrill.
heres an idea of a core using simple whiscash
+
whiscash and talonflame would make really great partners, with whiscash cockblocking the electrics that check talonflame, and talon checking the grass-types that scare whiscash. talon should be played aggressively early-mid game to punch holes in stuff like rotom-w or really any bulky water, with whiscash cleaning up late game. this core does have issues with bulky waters, particularly suicune or slowbro, so pairing this core with something like mega-venusaur is an excellent choice.
personally i prefer using an adamant nature+life orb with whiscash because
+2 252+ Atk Life Orb Whiscash Earthquake vs. 232 HP / 0 Def Mega Venusaur: 277-328 (77.1 - 91.3%) -- 25% chance to OHKO after Stealth Rock
+2 252+ Atk Life Orb Whiscash Double-Edge vs. 72 HP / 0 Def Latias: 290-342 (90.9 - 107.2%) -- guaranteed OHKO after Stealth Rock
+2 252+ Atk Life Orb Whiscash Double-Edge vs. 248 HP / 252+ Def Rotom-W: 183-216 (60.3 - 71.2%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
+2 252+ Atk Life Orb Whiscash Earthquake vs. 252 HP / 164+ Def Garchomp: 266-316 (63.3 - 75.2%) -- guaranteed 2HKO after Stealth Rock
while i recognize that you're going to be using whis late-game, while everything listed will be significantly weakened, i personally prefer it just to be more self-sufficent, and generally just less reliant on its teammates to secure a kill. you could go jolly if you want to speed tie with mega-zam/aero, but theyre not exactly very relevant in theorymon. overall its cool.
this mesprit is cancer, set it on fire
i dont see how zoroak adds to the meta at all except for a fucking incredible megagross partner+decently strong special priority user
honestly i dont like this jellicent change because it takes away the water immunity, and replaces it with something that only will take affect 30% more often than otherwise via scald burn. that wording was janky but im doing this on mobile so fml lol. i dont consider this to be much of a buff, frankly, and i dont think i would use this over slowking unless i desperately needed a spinblocker.
