Wulven Blood
Cost : 2cc
Class : Wulven
Type : Attachment, Attach to your Hero
"Everytime your Hero activated their Shadow Ability, all ally in your hand become a Wulven Type until the start of your next turn"

Card means to help Bloodfang for him not to get stuck playing Wulven ally eternally. I haven't think much about this though, could it get OP in Moonstalker hand ?
