Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If you control 2 or more Thunder monsters and this card is in your hand or GY: You can Special Summon this card, but banish it when it leaves the field. You can target 1 Xyz Monster you control; attach 2 Level 4 LIGHT Thunder monsters from your hand, face-up field, and/or GY to it as material, including this card you control. You can only use each effect of "Otonari Thunder" once per turn.
