Forum:Wind-up Shark Ruling

So here is the situation:

It is my turn, and in my hand I have Wind-up Shark and Wind-up Magician. My opponent controls an Effect Veiler in their hand, and for this situation assume their field is empty.

I normal summon Wind-up Magician. With the summon being successful, my opponent activates Effect Veiler targeting Magician. My question is, does Wind-up Shark lose it's chance to summon itself off of Wind-up Magician's summon? (since the last thing to happen is the opponent activating Effect Veiller)

Also, does this situation change if instead of Effect Veiller, they used Chain Disappearance?

Many thanks appreciated.
