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! Mothman!", Special Summon 1 "Danger! Mothman!" from your hand, and if you do, draw 1 card. If this card is discarded: You can have both players draw 1 card, then both players discard 1 card. You can only use this effect of "Danger! Mothman!" once per turn.
