Yeah, [card]shadowstep[/card] for 2 and [card]leeroy jenkins[/card] for 3... I don't know about the twins though. [card]Edwin vancleef[/card]?

1 - c'mon, how long can this go on? it's nerfed minion that summon a minion

2 - it's close to leeroy, but he's not in charge now

3 - yes, it's …

Smells like a shot in the dark.

Yeah, it's rogue deck. But not this.

Warning. Big hint. 

[spoiler]

First card summon a minion, it was was nerfed (1-2 line)

Second card is "fastest" card in game and it also was nerfed (3-4 line)

Third card name is hidden in text (5-6 line)

The deck was built around the fourth card and included all these cards

[/spoiler]

Ok, Sonya is closer...

Nothing is right.

1 - Think about why "nothing can we do with this".

2 - Superfast is key. We also "can do nothing with this" now.

3 - Third card name is hidden in text.

No to both. Each 2 lines is a card. Combined they lead to deck that builded around last card.

In the past there were two twins.
Now, nothing can we do with this.
Also there was one superfast guy.
Everyone talked about his warcry.

There is a traces from their steps.
The shadow is placed before them.
He's not teach them, but he preps.
Write here who has gathered them.

[card]Nethrandamus[/card]

[card]Dr. Boom[/card] itself?

[card]Beastmaster Leoroxx[/card] then

[card]Boommaster Flark[/card]

[card]Blastmaster Boom[/card]

Now what could that mean?

New core set cards are not collectible. I looked only on collectible cards (To exclude tokens and cards from other game modes.). In another case, I would immediately give the correct answer after Leper Gnome. (:
