But would this not lead to the rise of CBI or maybe CBP stuff?
That's not necessarily a bad thing. I'm not sure exactly what power level the designers/playtesters want to keep the game at, but since CBI and CBP stuff is weaker than CBN, so it is a step in the direction of lowering the general power level of the game.
I'm not sure I'd put the Ignoring Characters part on it, especially not for evil characters, first of all pre block ignore could be a problem, I'm not sure the extent of this, so it might not be a big issue, but we do have to be aware of the possible effects of adding another card that can stop some characters from blocking. If it's an artifact, it might not be too big an issue, since they are fairly easy to get rid of now, and are somewhat balanced by taking up your artifact slot (or at least an artifact slot, depending on if it could go somewhere else or not).
