I Have a very strong dislike for this card although it isn’t the card’s fault so much as it is the number 1 faction that abuses it. All in all the card is still too good for a 4 drop based on stats and ability. I’ll echo other posters with my confusion on why a card which clearly negates the play of battle pets was ever designed in the first place.
The problem with this card as I see it is simply that Vanar abuses the HELL out of it. They already had ridiculously good removal as it was and now they have more because you get punished in excess for building a board in the first 3 turns. All so they can use some combination of thunderhorn, hearth sister, and Aspect of Shimzar to clear your board while leaving up a threat.
Like I said, I hate the card so my criticism is certainly salt tainted, but I would at a minimum change the stat line to 4/4 for a 4 drop with a game changing ability.
