Putting it all together

We are not sure about the characters yet, since I didn’t agree for the warriors.

I thought of giving the characters different features based on their factors and everyone agrees.
Moreover, the number cards need to be part of the story too. Something you use to get, create, capture or save the characters.
We decided that the number cards will be a bit smaller than the usual size of playing cards and the answer cards will be bigger and maybe square.
