Standard

 Leftovers Anticipation Adamant / Brave
Moveset EVs
~ Earthquake
~ Stone Edge / Ice Beam
~ Aqua Tail / Waterfall / Surf
~ Toxic / Amnesia / Tickle
220 HP / 108 Atk / 180 Def

Simple tanking/attacking set. Tickle softens up opponents so Whiscash can attempt to take hits and dish out damage more effectively. Toxic is a good alternative to gradually wear down his counters. Amnesia can help him sponge special attacks to some degree.

Sleep Talk

 Life Orb / Leftovers Anticipation Adamant
Moveset EVs
~ Earthquake
~ Stone Edge / Ice Beam
~ Rest
~ Sleep Talk
220 HP / 108 Atk / 180 Def

Whiscash is fairly sturdy, so he can try to stick around with Rest and Sleep Talk. Stone Edge hits the Flying-types that are immune to his Earthquake, while Ice Beam helps a little against Grass-types. Life Orb gives his attacks some extra power, while Leftovers makes him more of a tank.

Choice Band

 Choice Band Anticipation Adamant
Moveset EVs
~ Earthquake
~ Stone Edge
~ Waterfall / Aqua Tail
~ Zen Headbutt / Spark
6 HP / 252 Atk / 252 Spe

While he may be slow, Whiscash has just enough in his physical movepool to attempt a Choice Band set. Zen Headbutt is his most powerful weapon against Grass/Poison-types like Victreebel, although it barely does more Earthquake. Spark isn't really needed since Stone Edge hits most Flying-types hard enough and Earthquake does more to most Water-types. It can help score some useful paralysis though and hits Mantine and Pelipper harder than Stone Edge.

Other Options

Besides Hydro Pump and Tickle (to soften up some foes or induce switches), nothing really.

EVs

HP, Attack, and Defense for the Standard set. For the Sleep Talker, add some Special Attack EVs if you're using Ice Beam and/or Surf.

Attack and Speed for the Choice Band set.

Opinion

Not much has changed for Whiscash. He is still overshadowed by Swampert and Quagsire, and now Gastrodon also outclasses him. However, he is a decent choice in NU thanks to his useful typing, and reasonable defenses.

Counters

Grass-types can take him with relative ease. Grass/Poison-types can't afford to take too many hits from Earthquake though, but they are immune to any attempts Whiscash may make to poison them on the switch.
