Continuous Trap
Your opponent cannot target "Palace of the Elemental Lords" you control with card effects, also it cannot be destroyed by card effects. Once per turn: You can Tribute 1 monster; Special Summon 1 "Elementsaber" monster from your Deck with a different original Attribute than that monster's. You can send this face-up card from the field to the GY; discard your entire hand, then add "Elemental Lord" monsters from your GY to your hand, equal to the number of cards discarded.
