Millstone⁣ - The List⁣ (Uncommon)⁣ [213]

Millstone allows you to pay two mana and tap it to make an opponent mill two cards. This can be effective in decks focused on milling strategies, disrupting opponents' plans while also thinning their libraries. However, it requires a consistent mana investment and can be slow against decks that don't rely heavily on their graveyards.
