Does Stupefy still allow you to draw a card if the target becomes illegal before resolution, similar to how Void Seeker works under the partial resolution rule?

Ruling: Yes, Stupefy works the same way as Void Seeker. You can still draw the card even if the target becomes illegal before resolution.

Nuances:

• The draw effect being on a separate line in Stupefy's text is only due to formatting constraints, not a functional difference in how the spell resolves
