## Description

Breaching Leviathan is a distinct creature card from the 2014 Magic: The Gathering Commander set, identified as card number 12 in the C14 edition. Designed as a high mana cost blue card, this 9/9 Leviathan serves as a formidable presence for players seeking to disrupt their opponents' strategies. The card features a mana value of 9, requiring a significant investment of resources to cast effectively from hand.

The primary mechanic of Breaching Leviathan triggers upon its entrance to the battlefield. If cast directly from the hand, the effect taps all non-blue creatures on the board. These affected creatures remain tapped and do not untap during their controllers' next untap step, effectively freezing the board state and providing a substantial tactical advantage. This ability makes the card a notable choice for control-based strategies within the Commander format.

Collectors and players alike value this card for its unique interaction with the board state and its place in the Commander product line. The 2014 release established a foundation for many powerful singleton formats, and Breaching Leviathan remains a relevant piece for those building decks around blue mana acceleration and disruption. For enthusiasts of the Magic: The Gathering trading card game, this card represents a key element of strategic depth and thematic consistency within the Commander series.
