I would like to see at least an one expansion. I really enjoy the game as is, but I also like having the option to change things up with new cards or maps.
I would like to see something like assassins.
In my head (granted I am no game designer and just vocing what I think would be cool) I see it as follows:
Assassins: worth 1
When an assassin is played pick a mercenary an opponant has on the table in front of them. That card is discarded and the assassin is now worth that amount of points +1. You can only play one assassin per battle.
So if you use the assassin to get rid of a 5, the assassin is now worth 6.
To balance it, it can even have the adverse effect of "If the winner of the battle played an assassin, the player to his left has control of the condottiere."
And to keep it light it could only add either 3 or 4 assassin cards to the game, between the constant shuffling and distribution of cards they can be a semi rare, yet tide turning occurance when one decides to show up amoung the, seemingly, never ending sea of Scarecrows.
