Hand Destruction's effect reads:
(Spell/Quick Play) Each player sends 2 cards from their hand to the graveyard, then each player discards 2 cards.
My question is simple: If I, or my opponent, have less than 2 cards in the hand, can I activate it? And also, will it resolve successfully if there's less than 2 cards on one's hand on its resolution time? (say, for example, if someone chains a trap which discards one card as a cost)
P.S.: There are old rulings from Upper Deck Entertainment that say it can't be activated, but they're not official anymore.
