Redemption will never make a hero that can bomb a hero in opponent's territory each attack, even at the cost of a card from hand.
The enhancement is ridiculously overpowered, especially in a side battle where you can almost certainly hit your opponent's characters in the main battle.
The enhancement should be Gold/Green, not Gold/Silver, if you are trying to represent the Passover.
The "Plague" identifier, while included on a few old Redemption cards, is not an identifier that the playtesters want to maintain.
Why does this hit characters and not evil characters?
