Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
3 Level 4 monsters Once per turn: You can detach 1 Xyz Material from this card, then activate 1 of these effects. Each effect can only be used once while this card is face-up on the field. ● Target 1 card your opponent controls; return that target to the hand. ● Send 1 random card from your opponent's hand to the Graveyard. ● Target 1 card in your opponent's Graveyard; banish that target.
