If you're only aiming to get the Evolve Shockwave card then just repeat Area/Battleground 5, the boss has only got 70 million health. If however you're trying to get a good rank, then you really need to plough on to the Area/Battleground 10, this Area will earn you around 1/2 million in total with an extra 2 million for a successful capture (he has 135 million health though). To be honest being a free player makes very little difference, I went though the campaign without buying any of the cards, but I do have a reasonable T2/T3 deck.
