Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Take 1 "Regenesis" monster from your Deck, and either add it to your hand or send it to the GY, or if you control a "Regenesis" monster, you can add 1 monster with 2500 ATK and DEF from your Deck to your hand instead. If this card is in your GY, except the turn it was sent there: You can banish it, then target 1 "Regenesis" monster in your GY; Special Summon it. You can only use each effect of "Regenesis" once per turn.
