Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Activate 1 of these effects; ● If you control a "Tistina" monster: Banish 1 card from your opponent's GY, face-down. ● If you control a "Tistina" monster Special Summoned from the Extra Deck: Banish all cards from your opponent's GY, face-down. You can banish this card from your GY, then target 1 "Tistina" monster in your GY; add it to your hand. You can only use 1 "Discordance of the Tistina" effect per turn, and only once that turn.
