Liquid Hearth added them and is treating them as gospel. I have minor doubts, as nothing is official until it's on bliz website, but this happened w/ the poisoned blade and it's real.
King's defender is a worse Fiery Win Axe. FWA is basically the best early card in the game since it (not always, but generally) ****s up aggro 2 for 1 (love dem anti aggro cards) but at 3 mana this is basically powermace. Which is a good card, but lacks the deathrattle.
How often will you have a 2 mana taunt (annoy o tron only reasonable one i can think of) that leads into the turn 3 weapon to get 1 more charge? Not very often.
The fact you *can* 3 for 1, potentially, is intriguing, and the fact FWA is so great that even at 3 mana a 3 attack/2 durability isnt totally worthless, but this card strikes me as a disappointment.
I don't see it popping in any current warrior deck (a lot of GPs run just 1 axe now as well) which means it has to have early game taunts to actually make use of the weapon battlecry. (And even when you do, it's not altogether that valuable, to be frank)
In arena these weapons have value (powermace with no mechs is still a reasonable draft pick, as is eaglehorn with no secrets) but warrior arena is still by far the worst and i dont really see this card changing that.
Sacred Warrior is a neat-o priest card. It's a more expensive, more durable lightwarden. Lightwardens are not run, (light of naaru IS) so I'm not sure if this card cracks a current priest list.
The priest lists involving deathlords and velens and so forth are very anti aggro, this actually is a more midrange-offensively driven card. Which is cool, since if they answer with sludge belcher you basically can clear it with a 4 drop, which is really tantalizing. A lot of players use senjins, and this is a better senjin (most of the time...) given the upside it offers.
Only fear is: Can this beat out Shredder? Shredders are a little worse in priest given you WANT high health minions so you can heal them, but man everytime i make a case for a different 4 drop over shredder I come back to the face shredder is OP OP.
I'm full of hope for this card, but priest isn't exactly known as a strong midrange class. This is neither a control nor aggro card, and only combos in unreal circumstances (with pyro/circles AFTER it stays alive a whole turn AND they dont have taunt) but maybe, just maybe, it could work.
Wilfred, as d104 (?) points out, should be a skin, rather than a class legend. A 4/4 for 6 is as weak as it gets (absolutely the worst stat mix) which means this can never be played on curve. He's an 8 mana play where you basically tempo your opponent by hopefully drawing something BIG (like Rag or alex or ysera or whatever giant etc) and slamming it on the board on turn 8. Oh, and if it doesn't get removed, the warlock is going to trash face.
The easy comparison is to Emperor. EMP is goat card, truly astonishing, and the main drawback with Wilfred (aside from it being legit weaker stats wise) is you prob get less of a mana reduction if you're playing a handlock type deck. (Or combo deck, like malylock - both cases your hand is full) It's also totally random what you draw, which is unknown and bad. It's also worse towards the end of the game as emp gives you the immediate benefit without going to fatigue
So yeah, it's basically not as good as perhaps the best card in the game. Well, that doesn't really help!
It seems like this card will warrant a shot, if only because of the insane things it is potentially capable of doing, but I think in a deck of just 30 cards it likely will not make the cut.
