A table for a dozen wizards, begun by its host

Rooms take up to twelve seats and the host begins the duel with whoever
is seated; a full table begins by itself. The lobby is a roster with a
bot seat and the host's begin button. The ledger pins the turn and your
own columns and scrolls sideways to the rest; the phone bar shows every
wizard's health; a wizard who is out watches the rest; each charmed
wizard gets their own gesture; an unnamed spell goes at whoever hurt you
last, else the weakest opponent; a stab has a target from the start.
