Deck build around making Plated Demolisher work.
Currently positive winrate on Masters.
It is surprisingly difficult for people to deal with it. Since it only sacrifices itself on the start of the enemy turn, you always seem to have time to add some armor to yourself, he will survive and value-trade or go face for 8.
Horngrinder also not to be underestimated. You play him and next turn you play one or two cards with armorgain and suddenly he becomes a really big guy <3
