Smothering Tithe

Whenever an opponent draws a card, that player
may pay {2}. If the player doesn't, you create a Treasure token. (It's an artifact with "{t}, Sacrifice this token: Add one mana of any color.")

"Under the weight of gold and duty, I collect what is owed to the crown. Each coin, a reminder that the kingdom's protection comes at a price, and prosperity is bought not just with valor, but with vigilance." —Knight of the Smothering Tithe
