Nick, Proletariat Unifier

{t}: Sacrifice a creature, then Break Chains 1.
Target Workforce gains any abilities the creature
had. (Put a +1/+1 counter on a Workforce you
control. If you don't control any, create a
0/0 human Workforce token first.)
When Nick, Proletariat Unifier dies, if you
remove a counter from a Workforce you control, regenerate Nick, Proletariat Unifier.
