Nice idea! Seems pretty powerful but not overly so since it needs captured Heroes to operate. What brigade(s) do you think would fit best? Maybe Purple/Clay since it's Jesus precedes that with "If you are truly My disciples" but he's talking to some of the Jews who at least somewhat believed Him but ultimately wanted to stone him. What do you think?
Also, here's a good way to format your ideas in the future to make them easy to read and make sure you hit all the information.
Card Name: Broken Chains
Type: Good Enhancement
Stats: 0/0 (?)
Brigade: Clay/Purple (?)
Identifier: X = # of Heroes released
Star Ability: Banish an Evil Enhancement with a capture ability from a deck, discard, or Reserve.
Regular Ability: Release any number of captured Heroes to negate and banish X evil cards in play. Cannot be prevented.
Reference: John 8:32
