This is the deck I used to defeat Noth the Plaguebringer Heroic Mode.

Make sure to upvote if you found this deck helpful and you've used it to successfully defeat him!

Reminder

1. It make take you a few tries to achieve victory, but keep trying. You will succeed! :)
2. Also some of the higher tier cards like Gurubashi Berserker, Sunwalker are not necessarily needed in most cases, but they do help.
3. At times you might encounter many Abominations & Flesheating Ghoul during your attempts. This is part of that "RNG LUCK" everyone needs. If this happens restart the fight as they effectively wipe your low health minions making you fail.
4. Don't be discouraged if #3 happened to you. This is a F2P deck, it requires a bit more "RNG LUCK" then normal decks. But you will succeed with minimal dust needed, just keep at it! :)

Mulligan

1. You want to mulligan your beginning hand for Warsong Commander. This is a must!
2. Cards like; Fiery War Axe, Acidic Swamp Ooze, Bloodfen Raptor, or Heroic Strike are also decent to have as well alongside Warsong Commander.

Strategy

1. Begin the game after you have done #1 on "Mulligan". Having any of the cards explained on #2 is also useful and not necessarily a must but strongly encouraged.
2. You will most likely skip your first turn, so on Turn 2 drop your 2 drops, and turn 3 drop your Warsong Commander as this whole strategy revolves around it.
3. After you have your Warsong Commander in play all other cards you drop with the exception of Sunwalker will have charge. Immediately begin going for the face!
4. Keep flooding the board and using Warsong Commander's ability to hit the face of any minion you drop. Never use minions to control the board!
5. Use your Fiery War Axe, Arcanite Reaper, Execute, Whirlwind to optimize board control. If no board control is needed I.E. Taunts then feel free to use the weapons for extra damage.
6. Only use Whirlwind in dire situations as most of your monsters have 2 health thus allowing Noth to use Mortal Coil on his following turn. Only use it to then Execute taunts so you can continue going for the face.
7. By turn 6 if you have had good draws, you've flooded your board, and haven't dealt with any pesky taunt. Noth should now be really low, around 23 or less. Hope you have Loatheb and use him on this turn immediately! The reason for that is Noth will use Plague immediately on his Turn 6, thus you need to prevent that in that crucial turn 6!
8. Noth will use mage secrets, most commonly Duplicate. Abuse this to your advantage. He often plays Bloodmage Thalnos and then Duplicate, so if you have a weapon kill it, making him waste his mana playing 2 of them further increasing your chance at victory.
9. Noth also uses Mortal Coil, but only when your minions are at 1 health, not matter if he has spell power or not. Remember to never drop down to 1, use Earthen Ring Farseers for this reason, if you needed to trade for some reason with 1 of his minions.
10. Use Kor'kron Elites to further deal damage.
11. Use Chargeto give Sunwalkers charge when you play them + 2 more attack making them a 6/5 with divine shield which will be useful to take down Noth's Spectral Knights and Skeletons as well as activate them for more damage which is the most crucial part.
12. Use Stampeding Kodo as both removal of a Mad Scientist, Unstable Ghoul, Flesheating Ghoul, or Bloodmage Thalnos plus the free charge for the extra 3 damage.
13. Use Gurubashi Berserker to board control the smaller minions, thus building him up in damage for a stronger next turn hit.
14. Be wary of Mad Scientist though, as he can give Noth Ice Block, Counterspell, Ice Barrier which would just ruin your day."
15. Only use your control for TAUNTS allow him to go for the face. You have Armor Up! & Shield Block to ensure you have extra health if you so need it!
