Is it Gral, the Shark maybe?

Yes. Its your go!

Lets go then ...

We were made to fight,
But what we want is to dance!
We might look strong,
But we will help enemies plans!

High Inquisitor Whitemane is the only one i can think of

She was one of the four horsemen tokens:

They were dk's so she was dead

Also the effect is to destroy the enemy hero if you have the all four horsemen so she wanted to destroy but now she revives

Also uther of the ebon blade and his tokens are in wild rn. But she is back in standard as a classic card

Volcanosaur then ?

Umm... Queen Carnassa?

Jfk guessed both true so his riddle should be solved. There is no problem here

Ding ding ding!!! True!

Its your turn JFK

Sadly all wrong. Think a card with scream and who counters it.

Both wrong. Think up in the sky like the place it is in, it doesnt mean it flies. Btw you are right about cry part, its a battlecry minion.

No, think more wildly

No, sorry

Here we go 

Fear what lurks in the swamp
But also up in the sky
You can't even scream
When you hear its cry

?

May i ask a short and easy riddle if you are not gonna?

Another idea: Argent Protector

Defender of Argus?
