Here my list for the event got pretty good result with it.
7/2 - 7/2 - 7/0 - 4/3 - 7/2 - 7/1
Brimstone the center of the deck u have to sac EACH turn a creature.
Tickling Grenadin : 5 dmg
Stone powder alchemist : 8 dmg
Piercing Grief : potentially 10 dmg (with two unblocked attack)
Rebel illuminator : 5 dmg
Madness : X dmg + 2
A lot of chump blocker or early aggro creature who can be sac too.
Creatures with revenge who coming back quickly with the doubbbbble draw.
Harsh rule global removal when oppenent board start to be fully and scary.
One single Stonescar leviathan to kill in one turn, efficient if the opponent gain more hp than u do dmg. (katra deck, heroes TSJ etc, sometimes feln control)
The card u wouldn't encounter in peculiar : Steward of the Past Statuary Maiden
Kill or stole/sac them a soon as possible steward and maiden destroy ur revenge opportunity and the getback of graveyard of the Shadowlands Guide. Keep a removal if u think the poppent play one or 2 of these.
Deck it's cheap, (only one legendary card), and really fun.
