Good day to you! This midrange deck does great against both aggro and control because you always have something strong to play, tons of card draw,  and enough value to out-control Control decks. This deck got me to legend with a 47-19 winrate.

Replacement Cards:

I know this deck isn't cheap, but most of the legendaries are replaceable. Naralex and Kargath are easily replacable. Kresh is nice to have (gets resummoned by N'zoth) but honestly isn't essential to the deck. Whatley is amazing in this deck (3/5 draw 3!) so I would recommend the craft, but if you're low on dust i suppose you can replace him. N'zoth is irreplacable. ----If you're missing any of these cards, replace them with Doctor Krastinov, Mor'shan Elite, Overlord Saurfang, Acidic Swamp Ooze, extra Minefield, Outrider's Axe, Rattlegore, Taelan Fordring, or Meeting Stone.---- Choose the ones you like, but I think Krastinov, Ooze, Taelan, and Saurfang have a natural fit in the deck. I haven't experimented with Conditioning, but it might be good in this deck.

Mulligan Guide:

This is not a control deck, so the most important part of this deck is to play something on curve every turn. Keep your low mana cards, keep Swordeater (amazing card), consider keeping Minefield and Kargath.  and consider keeping Whatley against slower decks. I usually wouldn't recommend keeping Circus Amalgam, Stage Dive, Kresh, or Stonemaul Anchorman.

Deck Strategy:

Always play on curve and always keep the pressure high. This deck isn't too hard to play so I'm sure you'll get the hang of the strategy yourself. Also, don't be afraid of playing N'zoth even if it only pulls 2-3 minions.

Match-ups:

Warlock: Free matchup lol. Play very aggressive so they can never have a chance to play Tickatus/Jaraxxus.

Druid: Free matchup. Celestial Druid can't react to the constant pressure, and you can easily clear the board if it's Token Druid.

Priest: Fair match-up because they have so many board clears and heals.Play smart instead of aggressive because they can clear the board with Hysteria and Souls Mirror, and heal with Samuro+Apotheosis, randomly generated flash heals and Desperate Prayers, and Lightshower Elementals+N'zoth. That beings said, this deck honestly does pretty well against Priest so don't worry too much.

Warrior: Usually in your favor for both Rush and C'thun Warrior. Play on curve.

Paladin: Usually in your favor. Focus on controlling the board because they have tons of healing.

Shaman: Usually in your favor. Be mindful of your hp. Once you gain board control, they can't pass through your taunts easily. Try to be more aggressive than them.

Hunter/Demon Hunter: Fair match-up. For Hunters, watch out for your hp and Trampling Rhinos. For Demon Hunters, be careful of the 8/8 Rush Demon (literally better than King Krush). Usually the matches will be very close, so every hp dealt will matter a lot.

Rogue: Usually easy match-up if you play on curve. For whatever reason, Poison Rogue does well against this deck, but my advice is to go face because Rogues can't heal.

Mage: Very difficult to win against all versions of Mage (bs Incanter's Mage, Wildfire Mage, and Freeze Mage). They have too much burst damage and too many ways to clear the board, and they can even heal from Ice Barrier! Play on curve and try to avoid taking any damage as best you can.

Good luck and have fun! This deck is tons of fun to play so I recommend trying it out.
