Hearts Assembly | JT Beaumont - Henri which I can recommend forHearts Assembly is a novelty visual effect. The three pips on the Three of Hearts assemble to a triangle shape, then they change into a big heart, the whole card also changes into an Ace of Hearts. Advantages: Very visual but practical. Easy to do. No difficult sleight of hand needed.
