Most decks don't run 1 strength units. As soon as the strength of your units starts going up, then the swing starts to go down. I do realize it's a pretty big power swing if done right, that's why I believe it should be a gold and not a silver. Having it be random is not the answer to make it balanced. It just makes it unbalanced and also frustrating on top of it.
Either way, BTM is going to get revised. I don't really like the concept of the card at all, I was merely thinking about the idea that was suggested of it becoming gold. If it became gold in its current state, no one would run in. That's a given fact, IMO. Maybe if it had no random effect it could be too strong, yeah.
Either way it's a card I don't like. Can't wait to see what CDPR does to it, but I really hope they change the concept a bit.
4RM3D Succubus is never a dead card, worst case scenario she's a 6 strength gold, so it's not the same. Also her effect isn't inherently weak to reset effects. Not saying she's better or worse, just stating it wouldn't be the same, and she wouldn't necessarily become useless.
