The Death Knight class is a feasible idea for Blizzard to put out in a later expansion since it is one of the playable classes in World of Warcraft. This class would definitely be represented by Arthas. His Hero Power would be Death Coil: Deal 1 damage to an enemy minion, restore 1 health to your hero. I made two class legendaries, an epic and a rare for the class that I think are pretty balanced. The class would focus around controlling the Deathrattle effects that are on the board. The Death Knight will be able to turn his opponents' Deathrattle effects against them or remove them entirely without completely silencing minions. His deck will also be built out of mostly Deathrattle minions because of some other class cards that I am currently devising. This class would lean more towards a control-based play style but an aggro play style would also be possible with Undertaker and another class-specific 1 drop. The mirror match would be very interesting indeed and it would require a lot of planning to ensure that your opponent does not steal or remove a Deathrattle.
Animate Dead is an unconventional approach at a board clear spell for the Death Knight. The Unstable Ghouls will keep your face safe and chain their Deathrattle effects to amount to a Flamestrike's worth of damage. It costs 1 less than Flamestrike because the damage is not dealt all in one shot, the damage is also dealt to your minions and the damage may not be boosted by Spell Damage. The advantage of this spell is that it provides you with minions to hit your opponent's face with or to potentially get more damage in on one of your opponent's beefier minions with the Ghouls' attacks. It initially seems like you're getting an Unstable Ghoul for free but in reality the fourth Ghoul is just going to die to the others' combined Deathrattle effects.
Frost Wyrm: This card is essentially a Frost Nova in a minion but it also freezes the enemy hero, preventing any weapon shenanigans. It can almost completely lock down your opponent for a turn when combined with Loatheb on turn 10. Could also be useful when combined with Doomsayer.
Anub'arak: This card is a genuine example of the Death Knight's main strength: Deathrattle control. Not only does Anub'arak provide a huge taunt minion that keeps your face safe from any late-game finishers barring Pyroblast or a lucky Ragnaros, he also permanently removes Deathrattle effects from your opponent's minions that are currently on the board as well as any minions that hit the board after Anub'arak does. This is not a Battlecry. This effect is always active and the Deathrattle effects on your opponent's minions do not reappear if Anub'arak leaves the board.
Frostmourne: This weapon might cause a resurgence of Harrison Jones in the meta. I had to take this into account when I made it, so I gave it some useful (but not broken) abilities to compensate for it being vulnerable to Harrison. It is essentially a stronger version of Ashbringer. Being a legendary card, only one of these can be in any Death Knight deck so it has to be a stronger-than-average weapon. It seemed too strong to cost 6 so I bumped it up to 7. Run this over Dr. Boom. It's a much better card. =P

Frost Wyrm: The last thing you'll be thinking about is why it's so cold outside. Then you'll just be a giant ice cube sitting in a meadow. Frost Wyrms do that.
Animate Dead: If only Kel'Thuzad had this kind of control over the dead!
Anub'arak: The former king of Azjol-Nerub. He was branded as a traitor by his Nerubian ilk because he was resurrected against his own will by the Lich King. Harsh.
Frostmourne: "Whomsoever takes up this blade shall wield power eternal. Just as the blade rends flesh, so must power scar the spirit."
Lol Blizzard chose to call the mechanic Divine Shield, not me. =P But I agree, it definitely shouldn't be called Divine if an undead creature has it... Perhaps a different kind of shield is in order: Unholy Shield that blocks the effects of the first spell used on the minion (including AoE spells). That would be a cool mechanic too!

Also keep in mind that Annoy-o-Tron exists. =P
