That Heroic Gluth fight... 
 
I have restarted it like 50 times now, and unfortanutely dumbly played out around 10-15 games where I didn't have oozes in my draw and he didn't have claws... but he always wins (gets a weapon around turn 7 or later).
I tried Hunter, Mage, Priest, nothing works.  The RNG hates me.  I get an Ooze in my starting hand?  He gets 2 weapons.  I get 2 Oozes?  He gets 3 of his weapon.  I get an Ooze with Duplicate on the board?  He never trades in to it.  I get a Water Elemental on the board and start freezing him in a match where he hasn't drawn a single weapon?  He top decks a Abomination.  I tried a good two dozen thought steals, not a single weapon.
What a stupid match.  I wouldn't mind it nearly as much if he only had 2 of his weapons, but I don't have HJ so all I get are 2 Oozes.  I guess another 25-50 tries and the stars will align just perfectly for a win.
