## Description

Bolas's Citadel enters the game as a formidable legendary artifact, originally released as part of the Magic Online Promos series in 2024. Identified by card number 99975, this card has established itself as a significant piece for collectors of Magic: The Gathering digital exclusives. Designed by artist Jonas De Ro, the card carries a rare designation within its promotional set, appealing to enthusiasts who value both its aesthetic and its mechanical impact on gameplay.

At its core, this product is defined by its unique ability to shift the rhythm of a match. The card allows you to look at the top card of your library at any time, providing crucial information for planning your next moves. More importantly, it enables you to play lands and cast spells directly from the top of your library. When you choose to cast a spell this way, you pay life equal to its mana value rather than its mana cost. This mechanic transforms the card from a static artifact into a dynamic engine, rewarding players who are willing to trade health for card advantage and tempo.

The card's ultimate ability offers a decisive burst of damage. By sacrificing ten nonland permanents, you can force each opponent to lose 10 life. This makes the card a potent finisher in late-game scenarios, turning a board full of resources into a devastating blow. Collectors often seek this promo not just for its utility in constructed formats, but for its status as a distinct release in the Magic Online calendar. It represents a key intersection of powerful gameplay and collectible identity, making it a notable entry for any serious MTG card collection.
