WARNING: VIBRANIUM BALLS REQUIRED TO READ FURTHER!

Hello Hearthpwn, this is my first guide here. I'm no pro or legend player, my highest rank ever was 3, but I believe many will find this deck worth trying and mastering, The core of this deck is Toast's dragon reno mage, with my favourite WATAFAKISGOINGON cards — Majordomo Executus and Coldarra Drake. With some adjustments, I ended up with this card list, and I bet everyone will find this deck challenging, hilariously fun and pretty usefull for climbing ladder or messing things up in Legend. Of course there are ways to climb ladder faster, but we all hate them with their huge axes or totally balanced 7/7 minions.

The dream

The absolute goal of this deck is to transform your Mage into 15 health Ragnaros with 7-20 armor, Ice Block on and 5 insects dead each turn. It's hard, but possible and won't last long — enemies too stubborn to surrender will die in approximately 1 turn.

Game plan

The game plan is pretty much like a typical Reno Mage. Against aggro you just keep them at bay with your board clears and removals, tank up with dragons and play a +29 Reno if needed. Most of the time your secret weapon is not needed here, so Coldarra drake can be played just to have something on board.

Agains control decks, you should save your resources and lure out enemy's. As soon as you feel that you are ready, play Majordomo Executus and trade it into enemy minions, while fortifying your own defenses. BE VERY CAREFUL playing Executus without Ice Block on. The only situation when this is possible is when you're 100% sure that enemy can't OTK you, like control warrior w/o Grommash Hellscream and with less then 5 cards left of his deck or Priest w/o Kazakus' potions and with no board presence. The  most challenging situation (and the most epic) is Ragnaros vs Jaraxxus. Try to play Executus before enemy plays Jaraxxus, otherwise you have zero chances to win (or just burst him down with some spells and potions).

Against bullshit like Jade decks, pray to the God of Topdecks, clear or  just freeze their board and burst them down or rush your Executus. It's possible but very unlikely, Jade decks are the most unfavorable matchup for any Kazakus deck.

Mulligan

Mulligan is similar to classic Reno Mage. Against aggro, hold cheap removals and board clears, ofc always hold Reno Jackson. Against control hold almost the same, add some draw potential and maybe any dragon for Netherspite Historian. Holding Ice Block or swapping it depends on your karma.

Card options

Mind Control Tech+Dirty Rat — adding them is personal choice, but imo two card slots may weaken your dragon synergy. This deck has more tempo then pure Reno deck, so MC Tech won't have many opportunities to be played.

Manic Soulcaster — most Reno Mages run this card, but i think she isn't needed here. Aggro matchups end before you can use her, and vs control i almost never need second Reno or Kazakus, game usually ends within last 3 cards drawn. But she's hot, so feel free to test it and leave a comment if she were useful to you. I mean like a card, you dirty pervert.

Don't know what's more to say. Share your thoughts and your experience in comments, and ask questions about this deck, I'll try to answer as good as I can, and will update this guide if I find something missing.
