'Cellulose nitrate was used to make dice from the late 1860s until the mid twentieth century, and remains stable for decades. Nitric acid is released in a process called outgassing. The dice cleave, crumble, and then implode.'

Considering that Jay could kill someone from across a room with a playing card IRL, I need to make a character based on him who also uses flammable explosive dice.
