Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is in your GY: You can Tribute 1 monster; Special Summon this card, then your opponent can add 1 monster from their GY to their hand. If this card is Special Summoned: You can target 2 of your banished monsters, including a Reptile monster; return them to the GY. You can only use each effect of "Aleirtt, the Ogdoadic Dark" once per turn.
