Is it possible to play this solo?
Viewing post in Pocket Monsters Manual jam comments
The original (and much bigger) game that used those rules, was a solo / gm-less coop game.
I did not finish it, but the rules were thought for a solo game and, in fact, I have other solo games in PT-BR that use similar rules.
Thus, I think it can be easily played solo with any oracle and a few personalized tables.
