If the new creature isn't on the battlefield as the first ability resolves, use its power when it left the battlefield to determine whether its controller may draw a card. Note that effects that reduced its power before it left the battlefield will apply.

The new creature's power is compared to the power of each other creature on the battlefield as the first ability resolves. If another creature has the same or higher power than the new creature's power, no one may draw a card.
