Are you serious?

As already mentioned this card is very flexible and can be either defensive or aggressive.
Senjin Shielmasta is a great card and a 5/3 stealth is extremely dangerous.
Both of the choices are beasts and will therefore have lots of synergy.
4 mana drop which will improve Druids curve immensely.
Helps progress your quest.
Synergy with Fandral.
etc.

I could see this making it in lots of different archetypes.

You shouldn’t directly compare cards with similar stat lines and abilities and decide that they are weak. That’s not really how the game works.

As a big Warlock fan I’d love to see Possessed Villager stay in the game. Love this card, think it suits Warlock so well and otherwise you’d always play 2 x argent squires or similar neutral 1 drop minion in your Zoo deck instead which is not thematic at all.

Also I’d love to see the spawned creature get the Demon sub type to help make the Demon archetype be more playable. Makes sense too.

I know Warlock is usually top tier so doesn’t really need more help but thought I’d suggest this anyway 🙂

I get your point about cards being over powered and agree with a lot of them but I also think that every class needs some over powered cards to make them work or make them interesting and fun to play. In fact those cards are usually the whole point you play that class in the first place. The only really unbalanced classes at the moment are Warrior and Shaman (and an underpowered Priest) and I would definitely change some of their cards.

You’re talking about changing or taking away some of the best cards from each class and while it makes sense in a way I also don’t really see the point as long as the power is evenly spread.

I think Fiery Waraxe is totally broken and one of the main reason why Warrior decks are so consistently good and usually top tier. It’s value is just insane as you can usually remove the first 2 minions the opponent plays while you can develop your own board. Of course there’s nothing you can do to the stats or mana cost that wouldn’t make it useless but I would love to see it have something like this…

“Take 2 damage when you attack”

or

“Take 3 damage when you equip”

…or something similar. This would fit the theme of “Fiery” and similar to the Flame Imp mechanic. The name Fiery always bothered me anyway. Why isn’t it just called Waraxe? Anyway it would not affect it’s effectiveness or decision to include it in any deck very much but at the same time it would provide a slight edge to decks trying to fight against the warriors ever increasing armour. It would also mean the Warrior has to decide is it worth taking to damage to take out a minion or attack face as it could put them within lethal range or drop their armour below shield bash range.
