I only ever get my deck ideas from this forum and then tweak it if necessary. For T50 I started with a cremation/destroyer rush, and now I use a speed entrobow.
So none of these ideas are mine. I used to play a version with shield (improved fog) and black holes for healing, but I find the precognition cards are a god-send in terms of increasing your damage output and not having to need those crutches.
