Intended to be played with cards like Brawl or Plague of Wrath

Small clarification: If you played, say, 2 Houndamsters, only one of them would count for buffing the Fiendhounds. This is to avoid shenanigans with stuff like the SoU Hero Power.

The 5/5 Ancient counts as a Treant, but not a demon. 

There was no Imprisoned for Shaman so i decided to make one.

" Finaly! That Demon is gone, the exorcism was a sucess, my work here is do...Oh damn, here again."

Real world priests were for exorcise demon and spirits out of people, and i've made that card to represent that, a stubborn demon that refuses to leave your minions alone. Some clarifications: Posses works just like magnetic, but can target all kind of minions,i decided to use that wording just for flavor reasons. And in case its not clear enough, when the possessed minion dies, its [Hearthstone Card (Possessive Poltergeist) Not Found] that returns to your hand, not the possessed minion.

Hope you liked it!

It's Valeera as a Shivarra (hence the name).

Fits into the Stealth Rogue archetype allowing it to multiple itself, giving you a lot of Stealth minions that may prove difficult for your opponent to deal with.

"Is he a dead Watcher, or a watcher of the dead?" "... Yes."

Inspired by Solarian Prime, I decided to make a kind of "spell taunt". I chose to make this effect symmetrical, as it would lead to some interesting trade-off on the player's side.

In WoW, Shirrak is a Watcher summoned by the Auchenai to protect the spirits of their dead, who uses a lot of spell-warping in battle. So, I figured he made a great choice for Priest, and for this effect.

I wanted to give Shirrak enough health to be able to make use of the effect, whilst also keeping the cost low enough to be useful as a combo-inhibitor before the game is over. I used Ysera as a guide for a health-oriented legendary with a powerful continuous ability.

In WoW, Lothraxion is a demon infused with the power of the Light. He has an ability called "Judgment Gaze" which increases the damage enemies receive for a time, so I tried to replicate that in Hearthstone. I could see him being used in a Control deck, fighting for the board.

Control Paladin has been a lost art for a long time; maybe Lothraxion can bring it back.

Druids have always been good at ramping Mana Crystals, so why not do that in a more sinister way? Ventarus can suck the lifeblood out of opposing minions to permanently ramp you, but only if you set him up with buffs or additional damage.

Inspired by [Hearthstone Card (Kobold Beserker) Not Found], Mannoroth gives his blood to fuel the savage horde and turn them into brutish blood-thirsty warriors. Every time he is damaged, he bleeds and another warrior arises who will go berserk and attack the first enemy it sees. 

A cheap demon that corrupts Treants and makes them threats to bigger walls. Witchwood Apple would be much better with this card, and various Treant cards came out over the next two years, so you could bet the Corruptor would have seen play!

He put all his black heart into tending theese thorns groves!

"Blacken Soul" (the 2nd Token) can be found here!

Stealth Rogue deck late game support.

Flavor Text: "Stop calling me a spellcaster! For the last time, I'm a FEL CASTER! Does literally NO ONE know the difference?!"

Fel Caster's flavor is sacrificing your hero's life to boost your spell damage. This can boost many small or AOE spells that could also widdle down your hero fairly quickly, but it could also work extremely well with burn damage to smorc your opponent before you die.

"Do you want a taste of my arcane magic? It's got a different flavor!"

The card is basically Arcane Missiles with Spell Damage +2 and a body. The downside is that you have to self-damage.

(This card is supposed to be part of the Ashes of Outland expansion, but AoO isn't one of the options yet.)

'Better received than Infernal III: Reforged.'

Inspired by the Deathforge, a location in Outland where Elementals are corrupted into Infernals by exposure to Fel energy.

Inspired by Despicable Dreadlord and Demonwrath, sort of combined to make a minion that fits the Warrior archetype.

Summon: The night beckons!
Attack: I hunger!

Flavor: She recently converted to the light, which pleased her sister is the Mistress of Pane who sells windows and shower doors.

Lore tie-in to Xavius' tendency to corrupt. 

A throwback to everyone's favorite card in 2016.

Note that it says "whenever" and NOT "after". It means Moragg is summoned before the spell resolves, which allows you to benefit from its spell damage.

"Success can be very attractive. For magic, of course."

Nothing more flavorful than a demon who needs pain to attack.  Can be used with various whirlwind effects in warrior or with Guardian Augmerchant and Rocket Augmerchant to great effect.

A simple Rogue minion based on a pun, i thought this fit the theme as Imp's aren't usually great at complex instructions.

I don't think this would play at all but it is only a common.

"He doesn't know the meaning of the word sneaky, nor any other words for that matter."

"He's especially furious at those other Demons. Why do they get all the synergy!?"

A rapid-fire tool for Mages to clear the board when no Flamestrike is available. Made to synergise with Raid the Sky Temple, Mana Cyclone and friends. Although it's easy to remove, your opponent will be forced to pay attention to it... or else.

It creates priceless weaponry forged in the dying embers of its own heart.

The Ur'zul are formed from the tormented bodies and souls of Korkul and fallen members of the Army of the Light. This is the perfect Demon for the Paladin class, consuming Silver Hand Recruits to grow into a terrifying foe.
