Haha that's funny because I had exactly the same deck and ended with 3-3.

As a guy that mostly just plays daily for gold and 1-2 a week in arena, this deck was amazing, but does cost quite a bit(was happy I had saved some :-D )

It's "fairly easy" to pilot, just usually mulligan hard for the early drops..AND remember Activators(playing a 2/1 dragon on turn 1 is much inferior to the 2/3)...especially if you plan on dropping the 2/2 buff a random card on turn 2

11/3 First Run
12/2 Second Run

Saw 2 mirror matches in the second run...it's a popular deck I guess :-D

Ive lost twice to warlocks...with some cube/demon shit, once to a mage, once by a paladin overrunning me(couldn't find my duskbreakers) and cant remember the last one :-D

Nice Deck 5-3
Lost 2x Aggro paladin and malygos Shaman :)

Went 9-3, 3 losses versus aggrodin. Cant complain :)

Thank you for the decklist.  It was my first time playing spiteful summoner and I went 9-3 :)

12-1 easy win, CONFIRMED!*¿!!

9:3, lost against rogue and agro paladins. Really fun deck to play.

10-3
Lost to Malygos druid, big priest, and I can't remember the 3rd. Very solid deck, seems powerful.

6-3 for me. Super fun deck to play! :) 

I'm testing it out but experimenting. Added Brann Brozebeard for all the dragon battlecries. I'll let you know how it does!

Edit: Went 11-3. Final loss was vs Paladin with a perfect draw and it was over before turn 6. Making a few more edits.

Sounds really good with Spiteful Summoner as well....

E: I've added in a Brann and a second Twilight Drake in exchange for a Twilight Guardian (Didn't have 2) and the Acolyte.... 10-3 on first run. This deck wrecks paladins without a problem.

Losses were against a secret mage (Got Aluneth), exodia mage, and a giant warlock.... Turn 4 coin into naga sea witch and 4 giants is just unbeatable.

Nice deck, 12-2.

6-3 and 2-3

lost against exodia mage and malganis cube warlock

5:3 for me....lost against exodia mage, big priest and aggro shaman with rng fiesta
