One thing about going back and clearing heroics is that you have access to current expansion cards that wasn't present when past Adventures were initially released. Going up against Gluth I realized that all he did was go face so I figured that Animated Armor + Major heals would be an easy solution for this fight.

This deck will carry you into late game where you need to eventually gain board control. If you play your heals right, you should be close to full health when fatigue hits.

You want to be careful spending your heals/animated armors. If you run out and he still has board control, you will lose. Save your echoes to be used on your Antique Healbot, Acidic Swamp Ooze, and Animated Armor.  Once Gluth's side of the board is full and you have multiple copies of armors/heals/etc, you can go ahead and use Flamestrike to wipe his minions out.

I did notice that once I put Brann on the board, he did trade for him. It could have also been because I had 4+ minions on the board at the time. I doubt the AI knew what Brann's effect was and that he needed to be dealt with. But either way, I was able to use his effect for a double Antique Healbot.
