Battlecruiser

Flying, Trample, Vigilance
When Battlecruiser attacks all other flying terran constructs gets +1/+1 until end of turn.
"Although it may take some time to get into action, once operational, the Battlecruiser is simply unmatched by any opposing unit - whether it be Protoss, Terran or Zerg."
—Raynor's Raiders blurb
