Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
(This card is always treated as an "Armored Xyz" card.) An Xyz Monster equipped with this card gains these effects. ● Cannot be destroyed by battle. ● Once per turn, if this card battled this turn (Quick Effect): You can return 1 card equipped to this card to the hand, then immediately after this effect resolves, Xyz Summon 1 WATER Xyz Monster. Once per turn, during the End Phase, if this card is in the GY because it was sent there this turn: You can equip this card to 1 Xyz Monster you control. You can only activate 1 "Reincarnation Unveiling Mail" per turn.
