Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Cannot be Normal Summoned/Set. Must first be Special Summoned from the hand by its own effect, and cannot be Special Summoned by other ways except from the GY by its own effect. If a "Guardian Eatos" is destroyed by battle or card effect and sent to your GY: You can Special Summon this card from your hand. When this card is Special Summoned: You can equip 1 "Reaper Scythe - Dreadscythe" from your Deck to this card. You cannot Normal or Special Summon monsters (but you can Normal Set). If this card is sent from the field to the GY: Send 1 card from your hand to the GY, and if you do, Special Summon this card from the GY. * The above text is unofficial and describes the card's functionality in the OCG.
