I was going to answer, then I noticed that your avatar isn't a joke. Sorry. I'm a jerk.

I would say yes for sure. He starts the turn with no action tokens, he uses the free action smoke cloud, there is then no restrictions as to what he can do. Next turn he will not be able to use the free action smoke cloud though, because he will have the action token from the last turn.

Because I like your Avatar, I will help you with your question.
Some peoples kids; always trying to throw stuff over the fence.

Because the special power reads that smoke cloud is a FREE action then you can use another action as you would normally.

Just like using any other FREE action such as Outwit or Perplex.

Squirrelfarmer is right. And so is Darthfatty!

BigSoph is correct.

BigSoph and Harpua are correct.
