Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
2+ Level 8 monsters Once per turn, you can also Xyz Summon "Gigantic "Champion" Sargas" by using 1 "Springans" Xyz Monster you control. (Transfer its materials to this card.) While this card has material: You can add 1 "Springans" or "Therion" card from your Deck to your hand. If material(s) are removed from a monster(s) on the field (except during the Damage Step): You can target 1 card on the field; either destroy it or return it to the hand. You can only use each effect of "Gigantic "Champion" Sargas" once per turn. * The above text is unofficial and describes the card's functionality in the OCG.
