apDrop's Kazakus Reno Mage (December 2016, Season 33)
Something like Ragnaros or Sylvanas.
Tempo Mage Deck List Guide (December 2016, Standard) - Season 33
There’s already quite a bit of AOE in the deck, but I mean you could a Firelands Portal for another Arcane Explosion.

That’s fine, you might actually cut a Dragonfire Potion.

Hard to say, but I’m sure it could get you to Rank 5 at least.

You could on Reddit: https://www.reddit.com/user/stonekeep
wiRer's Legend N'Zoth Control Shaman (December 2016, Season 33)
Barnes is a solid option.
Asmodai's Rank 1 Legend Kazakus Renolock (December 2016, Season 33)
It’s early removal (Totem Golem) and late game reach. You could run a Mind Control Tech probably.
Kazakus RenoLock Deck List Guide (March 2017, Standard) - Season 36
You could try Defender of Argus.
Budget (Cheap) Token Druid Deck List Guide - Mean Streets of Gadgetzan
It is a budget deck, it will be difficult to beat one of the currently best decks in the game.

Maybe second Violet Teacher and Conceal?

Budget (Cheap) C'Thun Priest Deck List Guide - Mean Streets of Gadgetzan
The dust cost at the bottom counts all of the cards. The 1,580 total removes the free C’Thun and C’Thun minions.
Thijs' ELC Superstars Dragon Pirate Warrior (December 2016)
Ravaging Ghoul might work.
J4CKIECHAN's Egg Druid (January 2017, Season 34)
Have you even played it? J4CKIE went from Rank 3 to Legend with this deck, which makes it better than awful. Not every deck is going to break the meta.
Maybe something like Feral Rage or Mire Keeper.
