Each player may call a vote targeting a spell or
ability on the stack as a state-based action once
each time they get priority. If they do, each player
vote "Allow" or "Disallow". If there's a majority
of "Disallow", the target is countered. If there's a
majority of "Allow", the target get "can't be
countered". The player who controls a target
countered this way get a Veto counter he can
consume to vote an additional time.
