There are some interesting pieces there. I had no idea there were so many different ones...
Something like a limited fire demon might be worth a try too. The piece regularly has a value of 83, so it is obviously a very powerful piece, but on a one-dimensional board, it could only burn pieces on either side of it. This would still allow up to a three piece capture. If we do decide to use it, I suggest we limit its moves so that it can only move like a kirin, or something like that. Maybe it could be the opposite value of the lion. Those other generals are definitely worth a look though, and I'll try incorporating them into some set-ups.
