Yoko-Zuna Sumo Spirit — Ruling

Effetto 1

This card's monster effect that sends your opponent's monsters to the Graveyard is a Trigger Effect. (It does not target.)
Monsters on your opponent's field that are in the same column as cards in your Pendulum Zones when the effect resolves are sent to the Graveyard. (If you have 2 cards in the Pendulum Zones, your opponent's monsters in the same columns are sent to the Graveyard, and in that case, those monsters are sent to the Graveyard simultaneously.)

The effect that returns this card to the hand is a Trigger Effect that activates once during the End Phase this card was Normal or flipped face-up.
If this card is changed to face-down Defense Position, or destroyed by battle or card effect and sent to the Graveyard, its effect to return it to the hand during the End Phase will not activate.
