Garrosh's Battlecry effect is the same to a card I once saw in the card creation contest. Credits to whoever made that one.

Totemic Power = Your minions have Taunt, Spell Damage +1 and Restore 1 health to all friendly characters at the end of your turn.

Bleed = Whenever your minion deals damage, you cast a spell, attack with a weapon any enemy character,  they will take an extra 1 damage.
Example: Casting fan of knives on Doppelgangster will kill them all instead of leaving three 2/1 minions. 
You need to deal damage first though before Bleed takes effect. Casting FoK on Scarlet Crusader will leave a 3/1 minion without the Divine Shield. 

Clarification: Only the discovered card gains the 'Fandral Effect'.

Cards that make your cards cost Health instead of mana will essentially cost 0. Felfire Potion, Hellfire, Flame Imp etc., will deal 0 damage to your hero.

Frostmourne has an extra effect which I decided not to include because it looks clunky with the amount of words.
It reads as "Whenever this kills an enemy minion, summon 2 minions that died this game and give them Taunt and Freeze.

Bleed is confusing, just say you deal one more damage. Otherwise they are good.

I don't think they will all be called "Deathstalker". That seems to be a title most fitting the hunter/deathknight combo.

Just lazy to think of fancy names for each of them so I just gave them the same title. 

I though something similar of the mage hero, but i'd say the hero power might be something like "deal 2(or 3) to a minion and freeze it"

Also, i think warlock hero power is too weak (maybe im wrong) and also is the prist battlecry , i think it would be better to cast "pint size potion" and the spell that kills a minion if it's 3 or lower attack in each minion

Updated with inclusion of the Lich King and his weapon, Frostmourne!

these are all really op compared to deathstalker rexxar, he brings great over time value, but ALL of these battlecries are just inherently better. Even anduin who is the weakest of your set, I mean, he does the same thing rexxar does but heals all allies for 2 as well. I mean, we have a baseline so at least have some balance to it.

These are all OP lul

moreover I don't think that every Hero card will have a boardclear as battlecry 

I didn't know Garrosh was secretly LoLs Sion.

I think one of your bigger mistakes is basing the rules of a completely new card-type of a single card and being hyper-focused on that single example; just because the Hero card that has been revealed is a 6-mana card with 5 armour does not mean that ALL Hero cards will be 6-mana cards with 5 armour. Why not consider this as something to help with ideas?

Yes, I know it's more like that Jaina is going to be a Banshee as opposed to a completely made up title, and yes I know this is fairly badly balanced (my original idea was to deal damage based on your opponents unspent mana but it made the text even smaller and tbf it does mean it's a fairly familiar effect), but still, just calling them all Deathstalker's feels cheap and you should also be brave enough to experiment and go crazy; Blizzard probably aren't gonna hold back.

I used Un'goro and Deathstalker Rexxar as references when I made these cards. See, all quests were 1 mana and had 5 mana cost rewards, which I think will also be applicable to these new hero cards, same cost , armor gain and all will have battlecry effects. As for their name, I was kinda lazy to think of specific titles for each of them as I thought it wouldn't matter that much. As for their battlecries, I based it on the assumption that all their effects will be at around 4-5 cost abilities. I did experiment on some things like the Shaman, Rogue and Warlock hero powers, introduction of passive hero powers.

edit.

These are a little bit ridiculous in power level. Most of these are nearly game-breaking and add effects to the game that don't even make sense. Man, do I love them, though.

Just made this one for fun. Might be OP, might be not, i dont know. I wanted to push the "stealth" archtype a little bit and also, let's be honnest, rogue crave for lifesteal. *Fingers crossed*

Have u noticed that u have put Sion (champion from League of legends) instead of Garrosh? Is it on some purpose or just mistake?

It was probably a mistake but I didnt really care about the card art as long as it depicted who my intended character to be. I cant seem to distinguish Sion and Garrosh. btw I dont play LoL. 

I think your priest card lacks a little flavor and could push the class identity a little more. Also, at 6 mana, a lot of the hero cards are really OP (like the paladin one especially).

IDK if this version necessarily does it, but I'd live to hear your feedback!

Interesting, I was definitely looking for someone who did something like this, and here we are.

It's definitely hard to think of options relative to what Blizzard is likely to do, since a lot of the more balanced options seem rather dull. 

It's understandable why the end result is people thinking up only op stuff, because it's considerably more interesting.

Really, to make this more believable, almost every card has to make people think that they might not want that in their deck.  Based on Blizzard's track record, only 2-3 deathknight cards will see regular play.
