Dr. Anton Zilvago

When Dr. Anton Zilvago enters the battlefield, create Dancing Mad, a legendary
6/4 black horror creature token with menace.
{t}, sacrifice Dancing Mad: rearrange the
order in which your opponents take their
turns. The turn order remains this way until
Dr. Anton Zilvago leaves the battlefield.
To him, all are puppets; he need only to grasp the strings.
