Refractor Cards utilize a special printing technology to create a unique visual effect. The cards refract light to create a prism or rainbow-like look and colorful shine. Most products include multiple types of refractors, each of which is named forby their different colors (Green Refractor, Blue Refractor, etc.). Each color is printed to a different quantity, and they tend to be numbered.
Refractor cards are more rare than common cards in the set, which means that collectors assign them greater value.
