Rule #1  You are not allowed to hero power, ever.  It ruins the consistency of Body Wrapper.
Rule #2  Zephrys the Great is primarily used to get that last bit of damage if your opponent happens to be at 30health when you try to OTK them.
Rule #3  If you have to use Zephrys, do so to clear the board near the end of the game.  Remember is only active after you've drawn your duplicates.
Rule #4  Body Wrapper will find Zephrys occasionally, but that's not necessarily a bad thing.  It still allows you to do a board clear, and then later the last bit of chip damage, but remember it goes to the top of your deck so you'll need either something to draw him right away or be able to survive your opponents next turn, or a Time Out.
Rule #5 Added a Faceless for Shirvallah.  Polymorphs kill this deck.  They aren't run much, but if you getted sheeped or Hexed, it's game over man.  Plague of Murlocs is the only thing that'll wreck you now.
