1. Detach all XYZ Materials: The XYZ Monster's XYZ Materials are detached and sent to the Extra Deck. This is a crucial part of the effect, as it allows for those materials to be used again for summoning other XYZ Monsters.
2. XYZ Monster is sent to the hand: The XYZ Monster itself is then sent to the hand of the player who controlled it.
Important Notes:
* No effect triggers: The act of returning an XYZ Monster to the hand does not trigger any specific effects on the XYZ Monster itself or the XYZ Materials.
* No "banishment" or "destruction": Returning an XYZ Monster to the hand is not the same as banishing it or destroying it. It simply returns to the owner's hand and can be used again.
Example:
If a player controls "Number 39: Utopia" with two XYZ Materials attached, and an opponent's card effect forces them to return "Number 39: Utopia" to their hand, the following occurs:
1. The two XYZ Materials are detached and sent to the Extra Deck.
2. "Number 39: Utopia" is sent to the player's hand.
The player can then potentially use the detached XYZ Materials to summon another XYZ Monster, or use "Number 39: Utopia" again by summoning it from their hand.
