Maybe another hint will clear you the answer:

For 400 dust I'm doing very little,
Miserably from one to other I jiggle,
That's how I try to avenge thee.
Maybe that's why nobody plays me.

I am a miserable soul of emotions,        Dark theme reference, probably from Old Gods or Frozen Throne
My anger, like billions of oceans,             
Swarms through all of my rivals.             I'm not sure what ot make of this part, maybe your opponent's get mad when the car is played
But when the agonizing finals
Come, I will simply be no more.               
No more will I see 1/1's at war,                 Has something to do with tokens I imagine.
No more will I strike at a jam.                   
Lastly, my favourite band is Wham!         I guess I'm too young to know this band, but it does exist. Might listen to a song or two for a clue.

For 400 dust I'm doing very little,         It's an Epic quality card, but a weak one at that
Miserably from one to other I jiggle,     
That's how I try to avenge thee.           I'm guessing it has to do with a Deathrattle
Maybe that's why nobody plays me.      Not a card you see on the ladder

After all of this, all I can come up with is Dark Wispers and Wisps of the Old Gods, both in the Druid class. One from Goblins vs. Gnomes, the other from Whispers of the Old Gods.

I analysed all the clues for like 10 minutes and I think Avenging Wrath fits every one of them perfectly, so that's my guess.

Yeah, I think you're right.

Yup, it's Avenging Wrath. You are up LeSergirius.

It's a bit broad, but I don't think it's too hard:

I am a part of something big,

But on my own I'm small and lowly,

4 is my magic number,

Since I don't like to be lonely. 

 Ogre Magi ?

Nope.

• Its gormok the impailer, im surprised you remember that card exists

It's actually none of those. I was referencing a deck archetype, but now I'm not sure if that's actually fair.

Maybe Prince Valanar ?

Nope. Think of "magic number 4" as in number of cards, not stats.

Otk pala

If this is indeed an archetype, then it is too broad, because:

  I am a part of something big,                   - part of something big, as in 4 cards out of 30 that make up entire archetype
  But on my own I'm small and lowly,        - those 4 cards synergize with the rest of the deck/class and without it they are useless
  4 is my magic number,                              - 4 cards making an archetype
  Since I don't like to be lonely.                   - I'm guessing these 4 cards summon minions, the archetype resolves around those 4 cards being minions or those 4 cards interact strongly with minions

Honestly I don't know where to even begin. We don't have any clues regarding this archetype, nor those 4 cards. We don't even know if those cards are unique (as in 4 different cards, not 2 cards times 2). As far as I can tell it can be anything.

You guys misunderstood me. The riddle references an archetype to define the card I thought of. Now that I convoluted this so much, I'll just say that it was Sorcerer's Apprentice (because it's a small minion and you need 4 on the board for the Exodia Mage combo).  Gormok the Impaler fits the riddle quite well though, so I'll pass it to SENA.

Sorry for taking so long, i forgot to check the thread.

"Paladins i fear,

Mages i smite,

I smash on the board

And make the trading stop."

Its a pretty difficult one, but you just need to think outside the box. (Btw its not a current meta card so dont go checking card winrates vs mages and paladins)
