Egg-Rattle Hunter. Carnivorous Cube really made this deck complete. The big turns with Rivendare and Feign Death/Play Dead make this so much fun

Concede Shaman with Giants, Zola the Gorgon and Spellstones. Ive had 4 Snow Giants with deathrattle and windfury on board at the same time. And ive also had 6 White Eyes. Fun deck that really kills Warlock(hex and devolve all their demons).....and not much else

Val'nyr Paladin with Leeroy, Lyneesa, and Blessed Champion. 30+ attack to the face is fun

I had more fun with fun decks last expansion but so far:

Wild Burgle Rogue w/ Kingsbane package - this deck could be converted to standard easily but I prefer wild due to the better variety of decks you come up against. 

Standard Buff Paladin - Go-to fun deck for multiple expansions now. Val'nyr makes it feel fresh

Recruit Warrior - Hard to make this work but when it does it's good fun

Woecleaver Warrior
Big Spell Mage
Cubelock is amazing to play, it's just too common these days.

Dragon Secret Mage

Deathrattle Malygos Rogue

Dead Man's Hand Warrior

1. Big warrior

2.  OTK pally

3. Mill rogue

For wild its

1. Control shammy 

2. Quest razakus priest

3. Highlander lock

Do you have a deck list for priest thief cube? I wanna try it! 

• 2x Potion of Madness
• 2x Shadow Madness
• 2x Pint-Size Potion
• 2x Carnivorous Cube
• 2x Youthful Brewmaster
• 2x Cabal Shadow Priest
• 1x Mind Control
• 2x Recombobulator (in Wild)

And then just any good card draw, control tools, good minions like Cabal Talon Priest or Obsidian Statue, stuff like Entomb or Dragonfire Potion. Suit it to your play style. It is by no means consistent or very good, but every 1/4 games are hilarious.
