The T Change from Jeff Prace is a stunning color change that's surprisingly easy to do. Additionally, unlike similar color changes, the T Change doesn't leave a reversed card in the center, so you're left completely clean.
From an ordinary deck, a card is turned face up and inserted into the center. Without any cover, the card visually morphs into another. It's simplicity is magical and the T Change is a great way to reveal a selected card regardless of your skill level.
