Does Smothering Tithe trigger if an opponent draws multiple cards from a single effect?

Smothering Tithe has a triggered ability that reads: "Whenever an opponent draws a card, that player may pay {2}. If they don't, you create a Treasure token." The key is understanding how the game processes multiple card draws.

Under CR 120.2, if an effect causes a player to draw multiple cards, each card is drawn one at a time in sequence. This means an effect like "draw three cards" actually generates three separate draw events, not one event of drawing three cards.

Because each card draw is a discrete event, Smothering Tithe's triggered ability triggers separately for each individual card drawn (CR 603.2). Each trigger goes on the stack separately, and for each one, the opponent has the opportunity to pay {2} or let you create a Treasure token.

Example: An opponent casts Concentrate, which says "Draw four cards." Smothering Tithe triggers four separate times. The opponent must pay {2} up to four times (total up to {8}) to prevent you from getting up to four Treasure tokens. They can choose to pay for some triggers and not others.

This makes Smothering Tithe extremely powerful against wheel effects or mass draw spells, as the opponent faces an escalating payment or you accumulate multiple Treasures from a single spell.
