My strategy for Instructor Razuvious was simple. Steal his overpowered Massive Runeblade weapon and use it against him. If you have a Runeblade, you can do 40 damage over 2 turns to a hero (assuming no taunts in the way) and so his 55 HP isn’t that much. Here’s my deck:

  • Target Dummy
  • Flash Heal x 2
  • Inner Fire x 2
  • Light of the Naaru
  • Mind Vision x 2
  • Power Word: Glory x 2
  • Power Word: Shield x 2
  • Convert
  • Divine Spirit x 2
  • Shadow Word: Pain x 2
  • Acidic Swamp Ooze x 2
  • Annoy-o-Tron
  • Thoughtsteal x 2
  • Velen’s Chosen x 2
  • Arcane Nullifier X-21 x 2
  • Sludge Belcher x 2
  • Holy Fire x 2
  • Confessor Paletress

I think I played this match up about 30 times before winning. It was difficult to steal the Runeblades. Sometimes I was able to steal one or two, but most often than not I wasn’t (I could only steal a max of 6 cards). I also didn’t have a lot of answers to them. I already put 2 Acidic Swamp Oozes (and I don’t have Harrison Jones). Arcane Nullifiers were useful because my other taunt minions would lose to Razuvious’ hero power. In my winning game, I stole one weapon (for 40 damage), did some damage with minions, and needed to draw both Holy Fires in order to win. I couldn’t think of a better strategy because those weapons are just too powerful. Hopefully there aren’t many other Heroic bosses that are a grind like this.
