# Generated Horizons Generated Horizons represents an interesting footnote in Magic's history as part of the Mystery Booster Playtest Cards from 2019. These cards were experimental designs never intended for Standard play, making them inherently collectible for players interested in design exploration and what-ifs. Collectors typically view playtest cards as curiosities that reveal Wizards' creative process rather than competitive staples. The nonfoil-only status limits variant options, which some collectors see as either a drawback or an authentic representation of their original purpose. For those focused on comprehensive Magic collections or design history, these cards hold appeal despite their unconventional origins and limited practical utility in actual gameplay.
