Basalt Monolith (PRM 43602 foil) is an artifact promo from Magic Online Promos printed as a foil. It enters tapped each untap step but can tap to add three colorless mana and can be untapped for {3}, enabling mana-sinking loops and combo interactions. Its repeated untap ability has historically been exploited to generate large or infinite mana in decks that can reduce or refund the untap cost.
