Forum:Most Unsporting Usage of Dark Smog

G'day. A question outside of mechanical rulings: Say my opponent controls "Dark Smog" and has 1 card in his hand. I use MST on Smog. He chains with Smog's effect, and then chains "The Forces of Darkness", returning 2 "Dark World" monsters from his Graveyard to his hand. For Smog, he discards 1 of the monsters he returned with Forces.

I suspect that he did not have a card to discard when he activated Smog's effect. Am I allowed to check his hand to verify this? Designless Square (talk • contribs) 03:01, December 4, 2011 (UTC)
