Blue isnt supposed to get burn, this is conditional but the condition is not very limiting. Make it "Whenever an opponent draws a card excluding the first card duing his or her draw step...." similar to Chains of Mephistophles.
Then it would just be worse then prodigal sorcerer in everyway. I know that blue isn't supposed to have the "pinging" abbility anymore. But the point was to create a "prodigal sorcerer" wannabe that while useful in limited could be very good in T1. But i still think it's a good card. Maibe change it's name and color and make it red?
