It's a moot point now since you went another direction, but in a round about way, I basically confirmed what D Pat suggested. Either A Mammoth or Wizard, then add the Rampage, Ambush, and Punisher. Like I said, you wanted a 4 ball BVP arsenal. Take away the redundancy and take what's left. If you would have added to the post after it started, you may have received more/better information. Many times, "build me an arsenal" posts like these are started and people never buy the balls so they aren't taken seriously. If you come back with some clarifications, people know you haven't abandoned the post.
