My strat was to get walkie-talkie at the start and get as many resource cards as possible (preferably scorium). Then all I had to do was balance the ratio of resource cards, "card generating cards" (gloves and minecarts are a must buy, and campfire is really good to have too), a few energy-generating cards and some a few gold-mines.
Ideally you should always have some card-generating card in your starting hand each turn, which increases the chance of hitting other card-generating cards, energy cards and especially gold mines.
Also any 0 energy cost cards with +1 card in them (ingots and helmets) are a must-buy because they're free resources with 0 downside.
Doing this should make things snowball late-game where you can get 50+ scorium per gold-mine and can chain tons of energy and card-generating cards together.
