## Description

Caves of Koilos is a dual-colored basic land card from the Magic: The Gathering 2015 core set, released in 2014. This foil rare card, numbered 241, was illustrated by Jim Nelson and serves as a functional resource for players building decks that require both white and black mana sources. As a land card with zero mana value, it enters the battlefield ready to support your early-game strategy without consuming your starting mana pool. The card’s design allows you to tap it to add either colorless mana, or choose to add one white or one black mana. This flexibility makes it particularly useful for commanders or limited formats where mana consistency is key. However, the power of this dual utility comes with a cost: every time you tap Caves of Koilos for colored mana, you take one damage. This mechanic balances its strategic value, requiring players to manage their life total carefully as they build their board presence. The foil treatment adds a distinct visual appeal to the card, making it a desirable addition to any binder or display. Whether you are looking to complete your M15 collection or need a reliable dual-color land for your Commander deck, this card represents a staple of the game’s history. The interplay between mana acceleration and life loss creates a unique decision point for every turn. This card embodies the strategic depth that Magic: The Gathering is known for, offering players a choice between safety and speed. Its enduring presence in the game’s history makes it a recognizable and respected piece of TCG culture.
