Frostwalk Bastion (MH1-240) is a Snow Land uncommon from Modern Horizons that can tap for colorless mana. For {1}{S} it becomes a 2/3 Construct artifact creature until end of turn while still remaining a land, and when it deals combat damage to a creature that creature is tapped and doesn't untap during its controller's next untap step. Its snow supertype matters for paying the {S} cost and for any interactions or decks that care about snow permanents.
