Challenge: To reveal or identify two cards solely thought of by two individuals.

This captivating effect has fascinated me for years. I’ve shared various methods previously, such as “Think Stop” in Automatic Placements and “Talons of the Hawk” and “Talons of the Bat” in Potpourri 2. However, these methods often feel too mathematical and lack the immediacy of selection and revelation that I find ideal.

Two notable yet contrasting methods are Ed Marlo’s “Double Thought, Single Deck” and Simon Aronson’s “Simon-Eyes.” Recently, I merged Marlo’s foundational idea with a concept from Aronson and an unpublished key card technique of my own to develop Twin Killing.

While it may not be flawless, this method represents a significant advancement over my previous offerings. It is not only straightforward but also incorporates a clever overhand shuffle at the beginning to effectively conceal the use of key cards. As with all techniques in this series, no sleight-of-hand is necessary.

Four distinct methods are presented, all achieving the same fundamental effect using the same key card technique. The only variation lies in how one of the two selections is made, all designed to address the weaknesses of the original Marlo effect.

The key advantage is that both cards are genuine mental selections, and the deck is cut both before and after the selection process.
