Okay, this is a surprise, but a welcome one.
First and foremost, though, I admit this is a lot to wrap my head around gameplay-wise, and I have to figure it's something I should probably not be doing in twilight morning hours. The format is honestly neat as an idea, and I think it could be developed even further with a bit more space and time for it? Like, I'd want to try this out sometime.
I suppose while I ended up with a handful of questions, the main one is about tiles - does the mechanic carry over where you cannot play Warriors/Items, if there are no more free tiles to use for it? The use of "may" is confusing me lightly here, I suppose.
Good job!
