Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Add 1 "Live☆Twin" or "Evil★Twin" Spell/Trap from your Deck to your hand. If you control a "Ki-sikil" monster and control a "Lil-la" monster, you can add 1 "Evil★Twin" monster from your Deck to your hand instead. You can only activate 1 "Secret Password" per turn.
