UPDATE: I've made a Monk class below:
Diablo was my favourite Blizzard game, pre hearthstone. For fun I made my 2 favourite characters into Heroes that would fit into hearthstone along with some cards! I posted this on reddit, I thought I'd share it here as well. I hope you enjoy it as much as I did making it.
Tyrael - Album
Story/Fluff - Tyrael is the Archangel of Justice, his exploits in battle became the stuff of legend. He is somewhat of a Maverick being a stalwart defender of Sanctuary. He wields the sword El'druin which he can summon to him at anytime.
Leader of Champions - Being the founder and the 'leader' of many groups such as the Horadrim, he can call upon the champions and heroes of Diablo. I tried to include all the playable characters and even some npcs. They also aid him with some spell cards.
Synergisitc Minions - His minions also all work together aiding and protecting each other, forming an almost 'inpenetrable' defence. The more board control you get the stronger they become.
Copy of Paladin? - He has no healing cards and relies on keeping his minions alive. Many of his spells focus on protecting them even at the cost of sacrificing health to do so.
Buff ups - He has more buffs than normal. Many have double effects so he can wipe the board, draw cards etc. whilst simulatenously empowering his minions.

Diablo Album
Story/Fluff - Al'Diabalos, the Lord of Terror, known more commonly as Diablo, is the youngest of the three Prime Evils as well as the main antagonist and title character of the Diablo game series, being its namesake. Amongst all demons known to humankind, he is considered the most powerful due to his ability to instill fear into the hearts of people with his name alone.
Demons- Similar to Warlock he has a tribal theme of Demon minions. This means the majority of his minions are demons and many spells interact specifcally with demons. Unlike the warlock thou he does willing sacrifice his life or discard cards, instead demons have powerful effects but wither away quickly when outliving their usefulness.
Iconic Characters - I tried to include as many of the bosses and terrifying minions you face in the game. As well as Diablos spells and abilities he uses against you. Remember Leoric and the Butcher? How about those annoying knights that cast Iron Maiden on you in Act 4, or his prime evil brothers in act 3 and 5!!
Destroy everything - Most spells hit everything with area of effects, including your own minions, which gives Diablo a unique deck design and approach to playing the game. There's still a wide variety so many deck types would be possible.
Enrage - His core minion speciality. Many minions benefit from being damaged, which combo's with his area of effect spells. Enrage isn't used much at all in other classes, except Grom. I found it perfect for the 'Hellish' theme.
2 Legendaries - I made 2 legendaries, this is so you can pick which one you prefer, one or the other. Conveniently there are exactly 2 other prime evils!
