When playing a spell like Stupefy that lets you draw a card, do you draw when you play it or when it resolves from the pile?

Ruling: You draw the card when Stupefy resolves from the chain, not when you initially play it.

Sequence:

• Play Stupefy and add it to the pile/chain
• Wait for opponent to react if they choose to
• When Stupefy resolves, follow the card text and draw the card
