Debt

Enchant target player. They must pay you {5}. You create a treasure token for each mana paid.
If the player in debt does not pay all the debt it increases by {1} for both the first and second of their turns not paid. If they are still in debt by the end of their third turn they must sacrifice creatures with
total mana cost equal to the amount that they are in debt for (tokens count as {1} mana each), you get a treasure token for each mana cost they sacrifice this
way, and you sacrifice Debt.
