If I have a LS in a site, and my opponent has the Wanderer and it's his turn, can he exchange the soul in my site with the wanderer or can he not do the exchange since a soul cannot be removed from a site once it's put in a site (unless a card specifies, such as Slaves LS, etc)?
If my opponent uses the wanderer and exchanges it with the NT Only soul, and then uses a draw ability during is turn which ends up pulling out his own NT Only soul, what happens at this point? Anything of note such as a restriction on having control of the same LS (with a special ability)?
