No, it didn’t come from the episode that just aired, and instead is from an older episode, for who knows what reason.
Densetsu no Fisherman Sansei / The Legendary Fisherman III
Water Warrior / Special Summon / Effect
LV7 2500/2000
Cannot be Normal Summoned/Set. Must be Special Summoned (from your hand) by Tributing 1 “The Legendary Fisherman” and cannot be Special Summoned by other ways. (1) When this card is Special Summoned: You can banish all monsters your opponent controls. This card cannot attack during this turn. (2) Cannot be destroyed by battle or effect, and is unaffected by Spell/Trap Effects. (3) Once per turn: You can return as many of your opponent’s banished cards to the Graveyard as possible, and if you do, one time for the rest of this turn, double the battle or effect damage your opponent would take.
