There is a related issue that the Nuclear deck is clearly the best deck. Improving Colony Influence is a start, since it brings the Diplomacy deck up to being on par with the other non-nuclear decks. That change also give a small boost to the other decks, but realistically the nuclear deck is still stronger.One thing I've tried (and liked) is to change the restriction on card buying. Right now, you are limited to 4 cards total, which should pretty much always be nuclear cards. Instead, I prefer limiting it to max 2 card per deck. While it's still a good idea to get 2 nuclear cards per turn, you are then faced with the (interesting) choice of what other deck(s) to buy from, in order to make use of your energy. This leads to every player having some nuclear cards, but also specializing in other decks; overall more strategic diversification.
