I was thinking of an interesting change to Shrine to the Heavens, that will create player interaction, while not actually changing anything with the card itself.
My thought was to change the Shrine to the Heavens to Morale. Much like the Omni Card Dugg, instead of 2% and at 100% you win the game. Perhaps it could be changed to you gain 2-5 morale, depending on a good balance for it, and at the end of the turn, if your morale is at 200 you win the game. This way your opponent has a chance to actually lower your objective, making you work harder for it.
Any thoughts on this?
