Copperhall Bailiff is a Unit.
How to Get
Beat the eleventh mission in Jekk's Bounty, "Copperhall Traitors".
Strategy
This card can shut down a lot of cheap, low attack cards, (such as Grenadin from various effects) and can also let Warcry units you played earlier such as Oni Ronin and Crownwatch Paladin be able to attack in without worrying about being blocked.
