The Underdark Beholder is a rare creature card from the 2021 Mystery Booster Playtest Cards set, identified as card number 49 in the CMB2 series. Designed as a six-mana Beholder, this Magic: The Gathering trading card game card features a mana cost of {4}{B}{B} and serves as a unique experiment in the game's design philosophy. As a Playtest card, it represents a specific iteration of gameplay mechanics that were explored by Wizards of the Coast before finalizing standard sets. The card’s design centers around a complex interaction involving ten eyestalk counters. When the Underdark Beholder enters the battlefield, it arrives with these counters, which act as a buffer against incoming damage. Instead of taking damage, counters are removed, and if none remain, the creature is sacrificed. This mechanic creates a high-stakes tactical element, rewarding players who can protect the Beholder while it attacks. Each time the Beholder attacks, it reveals cards from the library to find instants, sorceries, or enchantments with a converted mana cost lower than the number of remaining counters, allowing them to be cast for free. This dynamic makes the card a focal point for aggressive strategies that leverage library manipulation. Collectors of Magic: The Gathering often seek out Mystery Booster Playtest Cards for their novelty and historical significance within the game’s development. The Underdark Beholder, illustrated by Chris Tulach, stands out for its intricate rules text and the way it challenges players to manage resources and risk. Its status as a rare card from a limited playtest series adds to its appeal for enthusiasts looking to expand their knowledge of the game’s evolving mechanics. Whether for deck building experiments or collection display, this card offers a fascinating glimpse into the creative process behind one of the most popular trading card games.

Underdark Beholder enters the battlefield with ten eyestalk counters on it. If Underdark Beholder would be dealt damage, remove that many eyestalk counters from it instead. If you can't, sacrifice it. Whenever Underdark Beholder attacks, reveal cards from the top of your library until you reveal an instant, sorcery, or enchantment card with converted mana cost less than the number of eyestalk counters on Underdark Beholder. You may cast it without paying its mana cost. Shuffle your library.
