Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Each time a card(s) is sent from the field to the GY, place 1 Kaiju Counter on this card for each sent card (max. 5). Once per turn, while 3 or more Kaiju Counters are on this card: You can add 1 "Kaiju" monster from your Deck to your hand. If this card would be destroyed by a card effect, you can remove 1 Kaiju Counter from this card instead.
