Let me pose this question in the form of a scenario as it will be easier to ask:
My opponent has TEC Barnabas and TEC Silas in territory and rescues with CoW Samuel. I block with Egyptian Magicians and band in The Murdering Pharaoh, decreasing Samuel by 3/3 (now 1/1). My opponent plays Faith of Samuel (most thematically) and bands in Barnie and Silas, allowing him to draw 3 cards (of course Barnie pulls a soul out of my deck). I have initiative and play Every Man's Sword to discard Samuel.
Question: Does Faith of Samuel get discarded along with Samuel since it was played on Samuel, or does it remain in battle with Barnie and Silas? I know it would be discarded if, say it was a yellow enh that was played on Samuel, and since Barnie and Silas don't represent yellow it cannot remain on them in battle. If it remains with Barnie and Silas then it is significant because I would still have initiative to play an enh. So if I ended up playing an evil enh I would play Ruthless to target FoS, which would subsequently undo the band and draw and kick Barnie and Silas out of battle, leaving my opponent with no heroes in battle.
