In terms of rating you can do better than bronze 2 without a lot of cards, you just need some good strategies. I'm working on creating some bronze strategies post, you can check them out if you like. (I actually reached 2000+ rating with only 15000 power)
In terms of power, it's usually best to buy cheap gold cards!
