The latest Hearthstone expansion, Knights of the Frozen Throne, introduced a brand new type of card, the Hero Cards. They basically act the same way as Lord Jaraxxus, as they replace your hero with a Death Knight that has a brand new hero power and an active effect. The problem with these cards in Hearthstone’s Arena Mode is that they are basically a must-pick once you see them. If you go against a player that has a Hero Card, chances are that you’re going to lose no matter how good your deck is.
Granted, if you are in a winning position, and your opponent is really behind, then you’re probably going to win even if your opponent plays a Hero Card, but in the case where you’re both in the late-game and the board is even, playing a Hero Card is going to swing the odds in your favor in a huge way. The biggest offender is the Mage class and its Hero Card, Frost Lich Janna. This is a 9-mana card that gives you 5 armor, summons one Water Elemental, gives you a brand new hero power, and it makes all of your Elementals have Lifesteal. So, what’s the deal with Frost Lich Janna you ask? Why is she so powerful? Her power comes from her new hero power, called Icy Touch. With this hero power, you basically restrict your enemy from playing a 1-Health minion, as everything that you kill with this hero power spawns a Water Elemental. A Paladin that goes against this card basically can’t use his hero power at all, as you just ping his 1-Health Silver Hand Recruit and you get a Water Elemental, for two Mana.
The worst thing is that the power level of certain Hero Cards in Hearthstone is way above some others. For example, Frost Lich Janna, Scourgelord Garrosh, and Shadowreaper Anduin are much more powerful as they have an immediate effect on the board. Frost Lich Janna gets a Water Elemental on board, Scourgelord Garrosh gets a 4/3 weapon that also damages adjacent minions, and Shadowreaper Anduin destroys all 5-Attack minions on the board. You also have Malfurion the Pestilent that allows you to either summon 2 1/5 taunts or 2 1/2 spiders that are poisonous.
Surprisingly, the most powerful control Hero Card is Deathstalker Rexxar, as its Hero Power allows you to combine two beasts to create a Zombeast. This as you can guess, is a ridiculously powerful late-game Hero Power that allows you to constantly play huge minions with often devastating effects, but since most Hunter decks need to end the game early, this card isn’t as powerful when you actually use it in a game.
The fairest of these Hero Cards is Thrall, Deathseer. Shaman’s Hero Card needs a board for it to do anything, as it’s Battlecry transforms all of your minions into ones that cost 2 more mana, which is quite a big high roll card that could just win you the game, but if you get bad high-cost minions, it could also lose you the game.
These Hero Cards in Hearthstone are really not fun to play against, and I see them every couple of games, and since it’s really hard to play against them, especially in the late game, I’m not quite sure why Blizzard still hasn’t removed the from Arena.
