When something is put into play, who controls it and why?
The tokens will always come into play under your control, you cannot choose otherwise. 

From the comprehensive rules:


  110.2a If an effect instructs a player to put an object onto the battlefield, that object enters the
  battlefield under that player’s control unless the effect states otherwise.
  
  110.5a A token is both owned and controlled by the player under whose control it entered the
  battlefield.
