"Runes? Totems? I don't believe this Tauren have ever been to Druidic school!"
I had a couple of ideas this week, but eventually settled on this. Hamuul essentially doubles all healing you do, and any armour you gain for the rest of the game. Since Druid tends to focus mostly on single target heals, and armour being harder to gain without duplicates, I think this is a strong yet thematic card, without being too unbalanced. He doesn't provide any immediate benefit, but the long term benefit might just be worth building a Highlander deck around.
"Shields?! Where we're going we don't NEED shields!"
This is designed specifically to counteract the least creative decks that just throw up taunt after taunt after taunt. Balanced? Maybe, maybe not. But man would it feel good to play against warriors/wall-type priests...
