What does being "that guy" mean? being that idiot??
How OP do you think this card would be if you can lock down all spells/traps the opponent has in one turn? dumb noob kid.
Can you try and use your brain for once in your life? He's obviously complaining about the fact that you can use his effect once per turn against all enemy's backrows, considering this card is usually ran with many backrow it's an understandable complain. Are your parents cousins? Seems like it's the only logical explanation, without mentioning how rude you are for being a complete dumbass.
