I'm looking for the verb meaning "turn to dust" in the sense that the card can be broken into pieces and dust. The best candidates for me right now are "dismantle", "fission", "shatter", "break".
To give more context: I'm making a game where there are cards with souls embroidered into said cards. Later, the player can destroy the card which will give him the dust and the blank card in return. I'm looking for the verb describing the process of breaking the card in such specific way.
