Select 1 Monster Card and 2 non-Monster Cards from your hand. Your opponent randomly selects 1 card among them. If it is a Monster Card, it is Special Summoned and send the remaining 2 cards to the Graveyard. If not, send all the cards to the Graveyard.
Spell AND trap cards count as non monsters. Besides, there are good combinations for this. The problem with this card is not that it sucks. The problem is that it's situational and can hurt you if you don't have a backup plan.
