Photon Alexandra Queen

The monster effect of "Photon Alexandra Queen" is an Ignition Effect. (This effect does not target.)

When activating the effect, detach 1 Xyz Material from this card as a cost.

The effect of "return all monsters on the field to the owner's hand" and the effect of "then, the player(s) who had cards added to their hand by this effect take 300 damage for each" are not treated as occurring simultaneously.

When the effect "return all monsters on the field to the owner's hand" is applied, all monsters present in both players' Monster Zones are returned to their owners' hands. (This also applies to "Photon Alexandra Queen" itself, which is returned to its owner's Extra Deck instead of the hand.)

A player who has had one or more monsters added to their hand by the effect "return all monsters on the field to the owner's hand" will take damage from the effect "then, the player(s) who had cards added to their hand by this effect take 300 damage for each." (If monsters are added to both your hand and your opponent's hand, you and your opponent are treated as taking damage at the same time.)
