I would argue that the basic ability isnt unusable, but is certainly heavily reliant on the clan bonus it is paired with. For example,
Randy and
Warren make great use of the ability, and even power = opp power cards from attack manip clans can make decent use of the ability. You could even argue that the ability still retains a bit of use when it is found on a two star, gaining the advantage of winning ties, and thus forcing pillz.
That being said, I like the idea of a power = opp power +1 for the fact that it would be useful to all clans and would be a very flexible ability. The problem is that if it existed, eventually it would seep into the attack manip clans (strong, but possibly balancable, potentially over powered) and then the power manip clans. If they created a card like
Randy but with this ability I think it would be very frustrating. On the other hand if the ability were restricted in power/attack manip clans to only creating low star walls like
Chan, that could be quite fun, but you know eventually there would be a 4* or 5* released that always has 3 power over you and it would be just another
Spyke,
Caelus Cr, etc.
I am also interested in hearing people's thoughts on this, since the evolution of new powers is inevitable if the game wants to continue it's success over time.
