Materia [Opus XIII: Crystal Radiance]

You can play or more Light Characters onto the field.
When Materia enters the field, you may pay [X]. When you do so, search for 1 Light Forward of cost X and play it onto the field.
When a Light Forward other than Materia you control is put from the field into the Break Zone, draw 1 card. This effect will trigger only once per turn.
