Forum:Eradicator Epidemic Virus ruling

I was just testing my deck on WC2010, and I noticed that after I used EEV and destroyed my opponent's trap cards, he later used Mask of Darkness to add one to his hand. Does EEV still destroy it, and any Trap cards on the field, or does it only affect traps my opponent draws once I've already checked their hand and field? IDK if I can completely trust the video game. Lugia61617 (talk • contribs) 13:37, July 14, 2011 (UTC)
