Rulings
- Storm Caller's second effect only activates when it is destroyed while on the field. If it is destroyed while face-down, its second effect activates.
- If a Psychic-Type monster destroys your monster that is controlled by your opponent, you cannot place it on top of your Deck.
- You decide if you place your opponent's destroyed monster on top of their Deck at the end of the Damage Step, when monsters destroyed by battle are sent to the GY.
