8 of spades
Use this after forcing the 8 of spades and show that you had already predicted their card. (use your favourite force)
Marked Cards
Recently purchased split spades marked deck by David Blaine. They are the easiest cards to read, even at 5-6 feet and are of excellent quality. Marking is well hidden so will not be seen by spectators. (and not too expensive either)!!
