Forum:"Reveal"

Today I got the card Ambitious Gofer. It says that my opponent can reveal 1 monster in their hand to negate the card's effect, so I was wondering how revealing exactly works. I know it means that my opponent has to show me one of the monsters in their hand, but who chooses what monster that is? Can't my opponent just reveal the same monster turn after turn, rendering any second reveals useless? 87.195.20.124 (talk) 14:27, August 28, 2012 (UTC)
