Treasonous Commoners

When Treasonous Commoners enters the battlefield, you become the monarch.
As long as you're the monarch, you may draw
an extra card at the beginning of your endstep.
At the beginning of your upkeep, if you're the monarch, each opponent creates a 0/1 black Serf
creature token with "This creature gets +1/+0
for each other Serf you control."
