I watched a street peformer ask like 5 or 6 spectators to name a card both red 7s were named I remember a red ace was also named too forget which one tho. I usually keep the red 7's on bottom and top of the deck. I also keep in my back pack both 7 heart and diamonds svengali decks. Alot of people dont know about svengali decks still even tho they have been included in some magic sets. In fact I havent had anybody know that I might be using one. But the thumbtip my nephew busted me with using one. He knew about the thumbtip.
