Breeding Pool

Breeding Pool first appeared in the 2005 expansion Guildpact, representing the Simic Combine's laboratory environment within the city-plane of Ravnica. As a dual land that provides both green and blue mana, it became a cornerstone of competitive play, requiring a player to pay life for the privilege of immediate access to its colors. The card design was intended to balance the flexibility of land-based mana fixing with a tangible cost, establishing a precedent for the shock land cycle that remains central to the game's mechanics.

The Ravnica: Clue Edition release, featuring card 275, reimagines this classic land with aesthetics inspired by the atmospheric, investigative tone of the Clue board game. While the core mechanical function remains identical to its original printing, the artistic direction for this version emphasizes the architectural style of Ravnica’s specialized districts, blending the game's high-fantasy world-building with the distinctive, moody visual language of the crossover collaboration.
