DARK / Fiend / Effect
You can reveal this card in your hand; your opponent randomly chooses 1 card from your entire hand, then you discard the chosen card. Then, if the discarded card was not “Danger! Chupa Cu!”, Special Summon 1 “Danger! Chupa Cu!!” from your hand, and if you do, draw 1 card.
If this card is discarded: You can take control of 1 monster your opponent controls until the End Phase, also you gain LP equal to that monster's ATK. You can only use this effect of "Danger! Chupa Cu!" once per turn.
