According to the 1 hour recap special, Gengar doesn't know Psychic anymore and replaced it with Dazzling Gleam. They showed all of the current movesets of Ash's Pokemon except Dragonite's:

>Pikachu
Thunderbolt
Iron Tail
Electroweb
Quick Attack

>Gengar
Shadow Ball
Night Shade
Dazzling Gleam
Ice Punch

>Lucario
Double Team
Force Palm
Reversal
Aura Sphere

>Sirfetch'd
Night Slash
Brutal Swing
Fury Cutter
Detect

>Dracovish
Water Gun
Fishious Rend
Ice Fang

Pretty solid sets all around, but what the fuck is up with Lucario having nothing but Fighting type attacks and Sirfetch'd having zero Fighting type attacks?
