## Description

The 2021 Magic: The Gathering Mystery Booster Playtest card A Good Thing (Card #86) stands as a unique piece of the CMB2 set's experimental design. Crafted by artist Yoni Skolnik, this Rare Enchantment card features a complex mana cost of four generic, one white, and one black mana, resulting in a mana value of six. Collectors often appreciate this card for its distinctive identity within the broader Mystery Booster Playtest series, which was designed to test new mechanics and card frames rather than serve as a standard release.

In terms of gameplay, A Good Thing provides significant defensive utility while introducing a high-stakes risk. The card prevents spells and abilities from targeting, destroying, exiling, or causing the owner to sacrifice it. However, its upkeep trigger doubles your life total, creating a dangerous threshold where reaching 1,000 or more life causes you to lose the game. This dynamic makes it a fascinating subject for Magic: The Gathering enthusiasts who enjoy exploring the boundaries of card design and strategic depth. For many, adding this card to their collection represents an interest in the innovative and often unconventional elements that define the Mystery Booster Playtest experience.
