I'm probably the only one who figures this out alone lately since nobody has talked about it, so I made this one.
Before we go into it, most of these applies to wild format most of time, so Dread Raven is still an obvious meme card, but you can atleast see the possible combos with Dread Raven to enjoy.
There are only two classes that can do a reliable and effective way with Dread Ravens than the other seven classes. Right now I feel they can do amazing well in my theory if these cards can have a place in any deck, those two classes are Priest and Mage!
Two of these classes have their own several ways to play Dread Raven, by copying or resummoning Dread Ravens, the idea of this is to spam them on the board and threaten your opponent with Dread Raven standing still on the board.
Mage can OTK the opponent with Open the Waygate. For priest, I'm not sure if possible with Temporus in an easy way.
These two classes can do it very effectively so far, Rogue is excluded since shuffling them and playing 3 mana minion is less effective than copying and resummoning them.
While we are relying on Dread Raven, If you don't manage to draw one of these, The card could still be threatening in late game as they can easily multiplied and burst any hero's health at anytime if they are alive.
Decklists aren't here yet, but you can make it your own if you are a main mage player or main priest player. I have written little guide here as well for each two of them.
Note: Other class like Hunter can OTK opponent too, you can find those decks in this site by searching Dread Raven in the decklist, it is quite the only type of viable deck for Dread Raven right now.
Mage
Of course, this is a list of possible ways to do it, you don't need to add all of them at once in one deck, you would be lacking an answer to your opponent's threat. But hopefully there are some space for it, although I don't know which deck it goes in, so this is obviously made for a meme deck, feel free to try it out.
Cards with a copy mechanic from best to worst: Molten Reflection, Splitting Image, Duplicate, Echo of Medivh, Simulacrum, Hex Lord Malacrass,
A way to make Dread Ravens and copy spells more viable: Leyline Manipulator, Khadgar, Hex Lord Malacrass (More copy spells, more Dread Raven)
The OTK way:
Play the ordinary old quest mage, you can try Arcane Breath too if the dragons can have its place too. Copy them with Duplication and Simulacrum, Then discount it with Leyline Manipulator (reduce all copied Raven to 1!). Have four Dread Raven with Time Warp ready -> Deal 48 Damage.
Priest
With priest decks, not only you do have copy mechanics, but you have also many ways to resurrect it.
Yes yes, it may be the worst resurrection you can make... but the resurrecting this bird can be effective and not a dumb way at all, because of that, Dread Raven is probably the only worth minion to be resummoned compared to all other cheap minions.
If the big priest can spam the big minions, then you can spam it too!
Cards with a copy mechanic from best to worst: Herald Volazj (!!!), Grave Rune, Shadowy Figure, Mirage Caller, Vivid Nightmare, Seance, Power Word: Replicate.
Cards with resurrection mechanic from best to worst: Psychopomp, Resurrect, Mass Resurrection, Eternal Servitude (IMO, I don't like it since you will be spamming Dread Ravens anyways), and others that are weak and no synergistic ([Hearthstone Card (Sleeping Soul) Not Found], Onyx Bishop, etc)
There is possible way to make OTK with it, but I'm still not sure if it's worth to do so or not. All I can do is give you guys the hints, which are Temporus, and maybe Fate Weaver can be included as well.
And that's pretty much it, no other classes can do it effectively than them, we do have Greater Sapphire Spellstone for shaman, but that's only one way to do it for that class, and we need more ways to spam Dread Ravens.
Anyways, hope you guys will enjoy the new expansion, I will be of course trying out powerful cards first, but I'm also quite interested in meme cards too.
So, have a great day!
