Battlecry Loatheb often turns what would've been a good tempo turn into hero power + pass, or maybe hero power + Eternium Rover. Loatheb had some "bad" match-ups where it didn't hit anything and was still in every deck. This new card hits every single current meta deck except rez priest. It even hits itself, so the best way to stop this from wrecking you is to play it first. This might be the best card we've seen so far.
The wording on the 5 drop elemental makes me thing this is fake. 1/1 elementals that freeze? Freeze how? Is it like water elemental? Did they turn water elemental's effect into it's own keyword? Blizzard has taken shortcuts on wording in the past, but this is still a bit much.
