Okey Dokey todays episodes updated attack list is....drumroll please
Volkner:
Luxray:
Spark - hibana - ordered by Volkner at the very start of the episode during the gym battle after grotle attacks - is charged entirely in blue electricity and then electrically tackles opponent in a ball of blue
Thunderbolt - Not ordered but when Pikachu and Raichu are using their thunderbolts to charge the machine Luxray is using the exact same move in the exact same colour of electricity (yellow)
Ash:
Torterra(evolves in episode):
Leaf Storm - rīfu sutōmu - Used just when he evolves stated by either Volkner/Ash and then ordered to use by Ash later on in the episode
On a side note for Luxray, Bulbapedia is stating he used Discharge but i did not see it being used or hear it being ordered so someon might want to check that
