Using the DX Phase Riser is easy. First, you can hold it in gun mode as a regular form. When you want to switch to spark mode, just transform it. To trigger cool effects, insert one of the included Monster Ultra Dimension cards. You'll hear the monster's sound effects and even dialogue from the show. When handling the cards, be gentle to avoid any damage. Store the Phase Riser and cards in a dry place. If it gets dirty, use a soft, dry cloth to clean it. Enjoy your DX Phase Riser and have fun exploring the Ultra Dimension!
