A 2/4 Charge is arguably too strong as a solo minion without any other abilities (mostly arguable because Huffer exists, but he’s also random and easy to kill with his 2 health). Even one trigger makes it an immediate 3/5 with Charge, which is worth about 5 mana on top of destroying an opponents card in the Secret it counters which itself adds just more value and lets it take out at least 2 cards by itself. On top of that Deathstalker Rexxar exists, and this is under 5 mana and is therefore a possible pull, so “It’s a Legendary” doesn’t really excuse its power level.
 
It’s very much a tech card, and tech cards need to have some downside to them to prevent them from being auto-includes in every deck. It’s why Mind Control Tech got removed from the Arena, since it has decent stats and a really powerful ability if you can get it off that caused massive swings. If you saw it in your Arena pick, you usually took it. A 2/4 with Charge is too strong even if its ability never goes off to really balance it as a tech option.
 
Honestly you could make it a 2/3 Charge and it would probably be more fair as a punishing card (if a little understated. I think people would undervalue it a little), or make it a 2/4 without Charge so your opponent has a chance to deal with it before you destroy their secrets (although you could still give it Charge through Tundra Rhino, which is a workaround but is alright because it takes 2 cards and 8 mana to do).

@Ledvi  
If it’s gonna be shot by a fireball, that’s amazing value on it’s own and worth 4 mana even if it didn’t do anything else. But it does, it’s a beast with charge, that’s huge.
 
Think of it like a boar: 1/1 Charge, then with 2 extra mana you add 1/3 stats. That’s a fair card. But it’s a Legendary, so you have a narrow but powerful synergy, that’s the effect. The extra stat? That’s just too much. It can’t be dealt with by frostbolt and ping, that’s just evil and if mage goes second that’s even worse.
 
So, to make it a really powerful tech in any hunter deck, make it 2-4. It’s still OP, but it’s a legendary, so you’ll only have one.

@Marioland  
Now now…be nice. :)
 
Ledvi means well, it’s just that all of his cards are OP. Idk why. Adding up values isn’t exactly rocket science??
 
But yeah, 1st rule of TCGs:  
the players will always adjust to the best card in each category. It doesn’t matter if there are 100 perfectly balanced cards and just 1 that is slightly better than the rest: that 1 will become the norm.
 
I actually did some beta testing for a CCG where the owners didn’t understand this, and kept releasing ‘premium’ cards slightly ahead of the curve (they were basically being greedy bastard, obviously).
 
But this ALWAYS shot them in the foot, because you just can’t do that! All my work on balancing the meta became meaningless, because the meta standard was pushed elsewhere where people didn’t even have to look at the other cards. (since they had automatically become trash.)
 
So they had to undo the changes (and they actually tried this a few times: release an OP card, then immediately change it after the complaints) but that too is a horrible decision. Becaue you get the “all nerfs are bad” guys, who are ANOTHER type of idiot, who, despite all evidence, insist that the entire game should be brought up to the power level of that ONE card, and that ‘nerfing’ (balancing) ruins the game. All so that they don’t lose the card they had won/bought. So irresponsible.

@Marioland  
This.
 
Even if the Secret-owning ability of this card were never used it is worth running. A 2/5 charge beast for 3 would be insanely good. Next turn if you get Houndmaster you have a 4/7 taunter on turn 4 - and since it has charge and 5 HP it can probably kill something on turn 3, survive next turn, and get buffed.
 
Then you have the fact while it is on the board, opponent can’t play secrets, period. So against Hunter/Mage in particular it has a major major board-changing effect.
 
The card is cool. I like the Destroy effect. It’s just too good as it is.

@Ledvi  

 
You understand nothing about TCGs, don’t you?
 
You sere, every trading card game has a curve: a perfect equilibrium where a card is neither overpowered nor underpowered for the cost. Most cards are within a reasonable distance to this curve, like a 3 mana 3/4 or a 3 mana 3/3 with a minor upside, and the best of these are usually what make it into decks. Even then there are options among what cards to run in your 3 mana slot, because you could always switch that 3/3 out for a 3/4 and your deck wouldn’t be any better or worse for it since both cards are roughly equal. That way, every deck is different, yet balanced.
 
If something goes too far above the curve, you get problems like our friend Dr. Boom. Dr. Boom was so far above the curve that he was run even in decks that he doesn’t fit in (like Aggro Hunters, which would normally refuse anything with such a substantial cost to it). He quickly became meta-defining to the point where Big game Hunter became a requirement for any control deck to keep him at bay.
 
Now, let’s look at what you have here: a 2/5 with Charge, a massive upside against Secrets, and Beast synergy for 3 mana. If a 2/5 with Charge is worth 5 mana without any of that, why would giving it a bunch of upsides make it fair? How do you expect to kill this thing on turn 3 before it starts rampaging over everything in it’s path?
 
You say you understand, but you failed the very first requirement of TCG card creation and created the new Dr. Boom of Hearthstone: a card that will force everyone to build around it and it alone and annihilate everything else that doesn’t. Every card in a TCG has to be balanced carefully against the curve, or else secrets die out completely (and with it Freeze Mage, which is already looking worn down anyways) and Aggro Hunters take control over the entirety of the meta.
 
tl;dr: You say you understand what you’re doing, but know nothing and created a severely overpowered monster.

@Vree  
Not all cards have to be perfect or balance. That’s the beauty of Hearthstone.
 
You can call it denial, while I can call it unable to understand.

@Ledvi  
Stormwind Knight is 2/5 Charge for 4 mana. It should be obvious that you can’t add a significant bonus to it and then offer it for only 3 mana.
 
shrug You can keep denying and “failing to see” that your card’s busted and I can’t help you with that, but cards have an expected value at each cost and if it does not meet them, it’s imbalanced.

@Vree  
How would this card having one health be the same with Argent Horserider? He would have no protection with 1 health and with two secrets being countered, he would be left with 3 health, which is enough to be taken out by every spell and minions with 3 attack or higher. So once again, I fail to see how this card and Argent Horserider are the exact same.

@Ledvi  

 
I just KNEW you’d say that xD Obviously when discussing two similar cards one is going to have A that B does’t, and the other will have B that A doesn’t.
 
But given a choice between a Divine Shield on a chump and a destroy secrets, gain +1/+1 ability I’d take the 2nd any day.

@Vree  
But Argent Horserider has divine shield to protect itself from getting killed from Hero Powers, minions, and aoe/single spell damage.
 
This card won’t have any protection at all if it has 1 health and no divine shield or spell/hero powers immunity. And even if it gained two health. It can still be taken out by all spell cards.

@Ledvi  
Nope. I think you underestimate the power of cancelling secrets AS THEY’RE ABOUT TO HAPPEN, EVEN if they do not target this card in particular. (Eg. you can play this and STILL attack with another creature this turn against a Freezing Trap or Vaporize.)  
And this can cancel multiple secrets without an upper limit.
 
Compare Argent Horserider for example. With the +1/+1 bonuses on this it it clearly can not have more health than 1.

@Vree  
Of course you’re pulling my leg on the one health.  

Too cheap for such an awesome effects. Currently there is no card that could cancel Secrets as they become active, making a counter to them highly valuable. You could drop this to 1 health and it’d still be great.

I did by giving you guys the link to his artwork. That’s another way to credit an artist.

It’d be nice if the uploader credited the artist here (The artist is Assasin Monkey).

I think the word is Counter.

@MorningSun  
stormwind knight has the same exact stats with charge with just one more manacost. maybe make it 4 mana and a 2/4 would be great

@MorningSun  
I don’t know. Wouldn’t it get one shot by fireballs or frostbolts on the opponent’s next turn? I’m trying to make this legendary anti-mage mostly.

The statline on this is too high - if it’s going to have Charge it should probably only be a 2/3 at most. That makes it usable even without secrets, and with it becomes really really good.
