technically if your opponent is using 41 and pinchers 79 allows less counterplay. also it requires a 7, of which you only have 3. plus its energy is only 2 worse. still not worþ it þough
Honestly I think 77 is just too good for what it does. 79 feels pretty balanced, but having immunity on top of that is just such a big deal. It kind of says something that you can make a negative stone up to 100, and -77 is the best choice. Perhaps it would be balanced as 91.
the 77 interaction felt like a neat easter egg to uncover, but agreed, I'd either swap 11 with 13 or change 79's effect - maybe "return one of your stones in this row or column to your hand" like a repeatable tongs?
