Card intelligence brief
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.")

Sales, inventory, and broader Magic demand signals for Smothering Tithe.
RSG intelligence changes as sales, inventory, and market signals change. A demand signal is not a binding purchase offer.
Start with the closest functional alternatives, then narrow by what matters for your deck.
