yeah, sorry for asking, because I also think it's was an obvious one
but.. i just asked myself - what are the best and worst 3 drops you would (not) want to get. I was thinking whether or not people would include this card in their decks, if the good outcome has a bigger chance to occur.
It's a little hard to consider the viability of this card considering the full range of 3-drops we have in this game. Here's a few fun scenarios I could imagine: an enemy Pirate Warrior slamming into a Drakkari Defender and getting massively trolled, your hero getting a free heal off of Acolyte of Agony, a big-bodied minion like King Mukla just surviving and giving extra presence, an Acolyte of Pain giving you a free card, Mind Breaker showing up and being a pain to that Warrior that just wants to stack armor, Emperor Cobra destroying an enemy's minion, and the list goes on and on. We'll just have to see the play testing on this card before truly deciding its viability.
It is a very good defensive tool against aggro that tries to outrun you in the race for the face. Ignore their hydra and go face and stuff like that. Also, protection against weapon reach, I see it as a good tool against wild pirate warrior
