Guys, I really appreciate the ideas but I feel we have run off topic on this thread. The reason why I don't like the Sentinels is because they look different, not only on the backs but on the faces and the pips are very small so it also might be hard for the spectator to see what their card is or mistake it for another.
You said in your original post (aka the post that determines the topic of the thread) "I love to work with the Sentinels now because of their quality however I can't perform with them due to the fact that they look so different.
The last thing I want the spectator to say is "Oh, it's a trick deck." Even if I can give the deck to them the damage is done and that idea has gone through ALL of the spectators heads."
Your main reason in your original post for not wanting to use sentinels is because you don't want to be accused of using a trick deck. Since some holes got punched into that line of thinking you've conveniently changed your story to being concerned about your spectators being able to read the card. That's just bad form.
Considering your reason originally given for not performing with sentinels is fear of 'trick deck' thinking, I don't think we are getting off topic at all by discussing that issue.
Honestly, did you actually TRY performing with them? Did you get called out on it? Whats more if you expect to get called out you are that much more likely to have it happen.
If you treat Sentinels like any other cards, so will your spectator. You lead. They follow.
