6 Block for 0 is fine on Defect, but Boost Away is most exciting because it offers potential synergies with Statuses or All For One. I typically take one of these if it's offered in Act 1, and may add more if they turn out to be particularly good this run.
Very nice block output for a 0-cost card. The daze is a minor inconvenience that you can mitigate with card draw or turn to your advantage with powers like Adaptation or Smokestack.
