I just got finished up with a few PreReleases, and here's what I have to say about Team Galactic's Wager. For the most part, playing RPS was fun. I enjoyed playing Team Galactic's Wager every time. However, I went up against one opponent who kind of left me a bit confused. We played RPS two separate times, and each time we played my opponent seemed to throw their decision a split second later than me. I was about to say something, but I couldn't tell whether or not the opponent was cheating. I doubt he was (and I won RPS anyways), but I can easily see how confusion/frustration can come from this card. If an opponent cheats, there will be trouble... but a player may also intentionally accuse their opponent of cheating in an attempt to sabotage the outcome of the card. I know a lot of people who read this thread may not believe that people would be so manipulative, but when there are prizes on the line even the simplest of things can turn into big deals.
Here's a good tip for everyone who's still shaky about this card. First, when you get ready to play RPS with your opponent, go ahead and declare whether or not you want the sign to be thrown on "scissors" or on "shoot" (for our area "shoot" occurs on the fourth tap of the game, during which each player is to give a sign). This will prevent any confusion about when the sign is to be given. Second, make sure that both you and your opponent are tapping with just one hand. From what I've seen, most people stick out there left hand and hold it out palm-up, then proceed to tap their right hand on their left until a sign is given. This provides an opponent with the opportunity to cheat, as they take advantage of the "tap" that occurs to switch up their sign. For instance, while you may be giving paper as your fist comes down onto your palm, your opponent may bring their fist down to their palm, tap while you're giving paper, and then show scissors as their hand comes up from their palm. If there is no plane on which your opponent may tap and cheat, they can't get away with it; just use one hand in mid-air. Generally, you can set this standard by demonstrating to your opponent how you would like to play (you can do this while you establish the number of fist pumps you two will do). Last, make sure that you and your opponent pump your fists in time; it's the reason you both pump fists two or three times before you show a sign. After all of that, you should be able to easily identify a cheater. He or she will be the one who drastically delays the giving of a sign, to the point that there should be no argument about whether or not the opponent cheated. At this point, call a judge over and explain the situation.
Hopefully, that helps some people out there who are worried about getting cheated against with this card.
