Heavy Armour is much less useful than it used to be, with less damage based CC, and I can only see it really working well with Oty, Gravity shield, and perhaps Spark.
Shrieker, EQ are boring...
I think I will go with basilisk blood (Maybe I just like all the alchemy spells). It works as CC, and well with Voodoo doll. Not much better than Heavy Armour, but slightly more interesting.
Edit: Missed Stone Skin/Granite Skin, which is also a very interesting card. Almost voted for that instead.
(also BS, you will want to add Black Hole to the front page)
