Want to know how I make my pass invisible? Ask a question. If you ask a question, 99% of people will look up to answer, even if they've been burning you hard. It's just human nature. When I start my ACR, I "lose" the card in the deck, then look up at everyone and say, "You guys all remember what the card was, right?" When everyone looks up, I do my pass, although I could probably just cut the card to the top and no one would see it. As long as you have everyone's eyes, you can pretty much stick a raccoon in somebody's back pocket and get away with it (that's my raccoon to wallet trick, and I'm submitting it, so nobody steal it!).
