Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 "Snake-Eye" monster + 1 Illusion monster Must be either Fusion Summoned, or Special Summoned by sending 2 face-up Monster Cards from your Spell & Trap Zone to the GY. If this card is Special Summoned: You can target 1 face-up monster on the field; place it face-up in its owner's Spell & Trap Zone as a Continuous Spell. You can only use this effect of "Snake-Eyes Doomed Dragon" once per turn.
