Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn: You can send 1 "Elementsaber" monster from your hand to the GY, then target 1 "Elementsaber" monster (except "Elementsaber Aina") or "Elemental Lord" monster (that has been properly Summoned) in your GY; Special Summon it, ignoring its Summoning conditions. Once per turn, if this card is in the GY: You can declare 1 Attribute; this card in the GY becomes that Attribute until the end of this turn.
