Good suggestions Qv, I have some more for 2018:

-> Implement the new summon in group base. Only snake is a bit boring (That was announced in 3.0);

-> Change de group wheel and put moods instead of dangos or just made another system for ninja moods because is to hard to even think of changing a team if we never have moods for our new ninjas;

-> Put protection runes in group wheel aswell. Probably the best choice is take out Transformation Card. (Why not put transformation free?);

-> Put a counter in every treasure and summon treasure;

-> More ninjas in Home.

-> Implement "Protection Natures" in Tools, so we can try to match natures without mess the others;
