Necroskitter and clone/ board wipe interaction
I believe I am right but my friend says that Clone comes back as 0/0 as therefore dies. Who is right?


You are correct.

Clone's ability reads


  You may have Clone enter the battlefield as a copy of any creature on the battlefield.


This ability applies any time Clone enters the battlefield.  The person who controls Clone (in this case you) gets to choose a creature to copy as it enters the battlefield.  It will not die.
