Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
(This card is always treated as a "Millennium" card.) Control of this card cannot switch. You can discard this card; add 1 "Millennium Ankh" from your Deck to your hand. You can only use this effect of "Heart of the Blue-Eyes" once per turn. If this card is in your GY, and you have successfully activated "Millennium Ankh" this Duel, and your opponent Normal or Special Summons a monster(s) that is Level 8 or higher, or has 3000 or more ATK: You can send that monster to the GY, and if you do, Special Summon this card. You can only use this effect of "Heart of the Blue-Eyes" once per Duel.
