Warlock. Rare. Spell. Something with manipulating as it is their theme in Boomsday.

Well I was right about rare but wrong about class (it was neutral). Next one (with Omega sign on the helmet) is obviously Omega card, and it might be hunter epic Omega card.

I think it's neutral omega epic

 I don't know if they allowed more than one Omega card per class (neutral included), and we already have one Omega neutral epic card.

She kinda looks like a bounty hunter, so my guess is Hunter Common. Second choice is Mage Rare. 

Next card is an omega card, probably for mage (basing on teaser art)

Each card can be one of this four:

1. OP Druid or Warlock card

2. Combo piece for Rogue or Shaman decks

3. A card for a new archetype which is never gonna be played

4. Some random crap

it's an Omega card, not sure which class though. maybe Shaman as it has Blue eyes.

 Called it. 

I think next cad is a Warlock Lifesteal spell

 Does look like a Warlock cards artwork mate. 

I reckon the next one, although it could be warlock is probably another shaman card. 

I'm not 100% though, could go either way. The minion does look shaman-like though. 

I guess it's Warlock legendary btw amazing art

mage. rare. spell.

I hope it's the warlock legendary  can't wait anymore :D

I think this is going to be a Mage or Shaman common card. Something to do with discovering a spell maybe? and I'm gonna say it costs 5 mana.

epic warlock minion...

Mage legendary spell

Edit: probably related to spell power

Mage legendary

2 mana "Change your hero power into ... (maybe arcane related) that deals damage equal to your spell damage."

Next is the “wtf Blizzard” card guaranteed after the big wave of recent reveals.

Mage legendary spell, 8 mana
