Secret Base (V.3)⁣ - Unstable⁣ (Common)⁣ [165]

Secret Base is a land that can produce colourless mana or one mana of any colour, but the latter can only be used for spells that share a watermark with it. This makes it a strategic choice in decks that utilise cards from specific sets, allowing for flexible mana while maintaining a theme. However, its utility is limited to certain spells, so it's best suited for casual or themed play rather than competitive environments.
