Realistically, you need to pick the faction you want to play, rather than try to make it work using a bundle box.
Deathstorm is a fantastic value... but not so much if you want to play Necron or Tau, right?
One way to go is just buy the battleforce box of the faction you want to play. The value (compared to buying the models separately) is excellent, and most of the battleforces have all useful models -- as opposed to Deathstorm and Stormclaw, which are a phenomenal value, but have lots of models that nobody ever plays.
Then, just buy the mini softcover rulebook from someone... or ask nicely
