Very nice and intuitive faction ! I really like the core idea of spreading tokens that also grow your action economy.
I felt curious enough to try them out in a game and I had a good time ! However, I found it really complicated to score with this faction. I was never able to have more than 3 mushroom on the board, and they where all lightly defended. I just never had enough actions to also have at least 2 spore spared to score.
For example, If I want to place a new building and defend it with 2 warriors, I need to :
-Spend a spore to recruit, twice.
-Spend a spore to move
-Spend a spore to build
That's 4 spores already , just for the mushroom to be easily removed with one lucky attack. Also, each of your pieces is so valuable that I never felt that it was useful to use the death burst ability. It was quite an aggressive game, so maybe they would fare better with more peaceful factions !
Once again, great work, and I'm sure that with a few twist this faction could be truly great !
