Fanatical Firebrand is different from
Mogg Fanatic because it can't be activated when it's tapped. Mogg Fanatic doesn't see play and neither will Firebrand I think.
Ravenous Chupacabra is a great tool!
Dusk Leagion Zealot is efficient enough that it will find multiple homes. It's true that it is odd with Cuombajj Witches but it works well in TE and with Cavern Harpy for example.
Looking forward to many more playables! :D
