On the right we see Mar'gok's normal hero power, on the left is the justicar trueheart verson. Mar'gok likes to keep his hands clean if he can help it and uses his hero power to pump out larger minions quicker, this stacks each turn but goes away after you use it.

Enslaved Gronn: Very large taunt minion that gets bigger as you or your opponent toss out large monsters. Should be noted if you have reduced a minion down below 4 mana you don't get the effect activation. 

Arcane Displacement: I really wanted to make use of a few of Mar'gok's abilities before jumping into some more custom-hearthstone abilities and Arcane Displacement just felt right, offers a way to really put pressure on these aggro decks and keeps that board clear for you.

Ogre Smasher: What's an ogre without a little misdirection? The Ogre Smasher is a pretty generic 4 drop stat body, with smash included. He could be dropped down to 3/5 maybe wanted to keep his attack damage low since obviously you can buff these minions for massive face damage after clearing out those small minions, loses value if you're facing off against a bigger control deck.

Gorian Guard captain: Big body, gives that ogre ability to other opponents to maybe stop them from 100% killing that valuable target, might make it so you can give any minion the effect.

Arcane Might: Some more hard damage counters to clear out those mass spam decks with their accursed little rush minions. Rip Recruitadin.

Gorian Empire Axe: I really don't know how i feel about this, I honestly may remove it in favor of a minion but it does fit the theme somewhat, you essentially get a 3/3 for three, just two of that damage is going for the minion. 

Destructive Resonance: A mix between Swipe and consecration but you can't damage the hero so it's pure minion removal. Might be a wee bit strong?

Gorian arcanist: not much needs to be said here, generic 4/3 body with a twist on the ogre effect it's been done before.

Furious Ogre Lord: The more I look at this guy the more I feel like he's just a little to strong? Maybe it's just because of all the words on his card but i'll wait for everyones feedback.

Fierce Ogre Gladiator: Honestly the only thing that bugged me when i made this minion is that it has inspire on a basic card so he'll honestly probobly recive a rework or be turned into a TGT common.

Smash n' Bash: Here we see the mana play really pick up, particularly on mana cost with yours and your opponent's minions. Smash 'n bash functions as a larger single target minion removal, it has some pretty terrible value unless you control a big ol' six mana minion, in which case it's a mana cheaper than your usual fireball.

Arcane Power!: Essentially this classes 3 mana get 2 cards spell, as Mar'gok is technically a mage and most of their spells have some high control use it felt pretty lore friendly to pop this one in there.

Ogre Magi Warleader: Some card advantage play on one of the smaller ogres, as you guys can see most of the spells for this class are relatively cheap removal as you'll be relying on those so you can make the most use of your hero power and get an advantage in the early game by focusing on getting out a high value minion as early as possible so you're kind of trading up for the standard Sorcerer King play in favor of speeding up your hand control, useful incase you have a bad starting hand.

Unstable Arcane Rune: Some more control, essentially a less magey way of freezing them all while retaining the classes feel.

Frostfire Slaver: Ayyy mana play, and freezes all the tiny minions! Stop that face damage in it's tracks!

Twilight's hammer Magi: Based on the fact Cho'Gall rose to position of the Twilight's Hammer Clan before it became all old god influenced, this Disciple of the crazed ogre magi is pretty good at pumping up your removal spells!

Ogre Slaver: Continuing the Sorcerer kings love for mana the ogre slaver follows the Gnomish Mind control Technician with it's 4 or more minion condition, and the ogre slaver love smashing those disobedient slave uprisings!

Runic Soul Blade: Kind of feels out of place but it is a caster sword so what they hey! (Not a whole lot of caster ogre weapons to be fair!) the Runic soul blade lets you smash your foes into oblivion, as long as you've got a smasher already on your side of the field anyways!

Ogre Slag Slinger: Some more enemy minion control to keep those aggro decks at bay the Ogre slag slinger will assuredly help you with those pesky 1/1's and 3/2's, as long as you've got another big guy to keep him company anyways.

Ogre Butter Knife: Butter knife to an ogre, giant two handed sword to a human, this blade gets bigger and more useful if your opponent is pulling some early game shinangins, one of the few non-spell early cards for the Ogres.

Ogre Murloc Hurler: What would a new class be without dat murloc synergy. The Ogre Murloc hurler will throw all your little guys straight into the battle, killing them in the process but hopefully not before taking out the enemy minions!

Primal Ogre Lord: Terrible body stats for a 7 mana minion, especially since has no real ability he depends on your ogres survivability to beef him up, make sure your field is full of big guys!

Frostfire Slag Shaman: Ogres hate it when puny slaves try to rise up and thats why the gorian empire has these guys, the Slag shaman is a big damage board clear but he'll hit your guys too if you're not careful. Valuable board clear though.

Ogre Shadowmage: A mistype that'll be corrected when I go back to fix these he makes it so whenever smash damage is dealt instead of dealing it to the enemy hero it is dealt in a manner similar to Avenging Wrath, trading up face damage for some extra Board control.

Frostfire Ogre Magi: Smasher that gets bigger to get more smash value but starts off as a pretty weak body. 

Gorian Frost Mage: This was a fun card when i'd finally settled on the effect, we haven't really seen this yet and it was to good for some more control fun.

Ogre Thinker: I didn't even know ogres had these! He's pretty good at smashing mechs, not so much with building them though!

Arcane Explosives: Some more rng spell stuff, and Mar'Gok has some interesting spells around that mana range.

Gorian War Construct: While ogre mechs here may be more golem than machine this war construct can smash up with the ogres, even if it's a one time deal. Essentially the Gorian War Construct deals 4 damage to an enemy minion and the extra damage is smashed to the hero.

Runic Beserker: Pretty basic card in terms of ideaology but has some big effect on the game. Low hp to make sure that smash value isn't too good.

Mystical Bashing: Shadowflame that's a bit more conditional, one of the stronger Sorcerer King spells i've made thus far but it makes it's epic rarity deserved.

Primal Gronn: I really wanted to get in touch with the BC gronn (Gruul's kids) who took great joy in hunting black dragons, so why not destroy your dragons for smash! Normal body for that sort of mana cost, however this really forces you to decide on if you want to smash or get that dragon out. Low cost dragons would go against your hero power so just having them there to give this guy smash costs two cards so really forces you to think about the situation you're in and the value of losing that dragon.

Ogre Slag Ascendent: Starting to run out of viable Ogre wow art! Stronger minion that is forces to be played on or after turn four rather than pumping him out. Some more mana and minion play that just really goes with the class' game play style I rather like him.

Incineration Beam: The first real hard minion removal for Mar'gok.

Truesteel War Cleaver: Interesting way to clear out minions and depending on your play style you could very well be spamming your hero power to whip out a bigger minion.

Furious Upheaval: Some more of that hardcore bashing, lose a minion but an extra bump for that board clear.

Gorian Mender: Keep your minions up, whats not to like? Lets you keep control of the board and synergizes with an epic below!

Runic Implosion: More likely to target a big minion if you can but still just as useful if you can kill a 3 mana minion.

Ogre Strength: This was something i'd been waiting to add in, finally a way to smash even harder. Based on the normal 2 mana deal 3 damage standard for spells.

Imperator's Guard: A very sticky taunt minion to hopefully survive even in the late game. Phenomenal against those rush decks if you get him out.

Gorian Magic Breaker: Some spell safety here and gives you some advantage as Sorcerer King focuses more on minions that are large and most of their spells are low cost.
