First, let me say that with the new cards in Dreamlands, Haster ROCKS, I finally took out my daughter's Agency/Miskotonic combo in a best-out-of-three match!
However, I hope I am interpreting "Bringer of Fire" correctly... do you only need 2 copies of BoF out to exhaust and destroy a character (see you later, Marshall Greene!), or must you have all three copies of BoF in play?
