This is P.T.P.S.W Plot Twist Portal Shuffle Warlock.
Each copy of Portal Keeper and Portal Overfiend shuffle 3 Portals into your deck. When you draw one of these Portals, you summon a 2/2 Demon with Rush, for free! Baneful Banker and Augmented Elekk can help you shuffle even more portals in the deck. Banker and Elekk can also shuffle multiple Aranasi Broodmother into deck if you need more health.
Plot Twist and your Hero Power lets you draw these cards even easier.
If played right, the deck will most likely grind your opponent out of resources.
Archivist Elusiana helps against Bomb Warrior if your deck i filled with too many bombs and make Hakkar’s Deathrattle one sided.
