Pop Quiz 1

Pop Quizzes will be given out whenever the hell I feel like giving them to you guys! I decided all the Obelisk dorm patrons should know the answer to this (should >_>) so I wanted to give it to you guys as a bit of a challenge. I want you guys to really test yourselves and try not to google.

Here is your situation: You have Wind-Up Factory on the field, and Magician and Shark in hand.

You normal summon Magician, and special summon Shark, activating both factory and Magician.

You plan to summon Shark with Magician, and add Shark to hand from Factory.

Is what I did here a legal play?

(I special summoned the Shark I added from my deck from the Shark Magician summoned.)

I want you to PM me how this works or why it doesn't work. A fully answered explanation merits 50 dp.





inb4 all the staff tell me to shut up with this ruling already.

Your tip: the answer is on the website somewhere.
