Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
This card's name becomes "Skull Servant" while in the GY. If a Level 3 or lower Zombie monster(s) you control would be destroyed by battle or card effect, you can discard this card, instead. If this card is sent to the GY: You can add 2 monsters with different names from your Deck to your hand, except "Wightbaking", that are either "Skull Servant" or mention it, then discard 1 card. You can only use this effect of "Wightbaking" once per turn.
