Thaddius is the fourth and final boss of the Construct Quarter, the fourth wing of the Curse of Naxxramas. Most of the information in this guide is aimed at Heroic mode, but everything presented here can also be helpful to defeat the Normal mode of the boss.

Thaddius Normal Thaddius Heroic

1. Health, Hero Power, Cards, Etc.

Normal Heroic
Health 30 45
Hero Power Polarity Shift is on auto cast (it costs 0 mana) and swap the Attack and Health of all minions.
Deck
Extra A 7/4 Stalagg and a 4/7 Feugen appear on the board on Thaddius' first turn, with no text (meaning that they will not summon Thaddius after they both die).

2. Video

We put up a video on Youtube to show you how to defeat Thaddius.

3. Strategy and Deck Building

When building a deck to beat Thaddius, your main focus will be dealing with Feugen and Stalagg at the start of the encounter. Since they are without Deathrattle, they will have no interaction with your own Feugen and Stalagg, should you decide to play these cards.

The easiest way to deal with Thaddius' Feugen and Stalagg is to play Big Game Hunter and other similar class cards, such as Corruption, Soulfire, Naturalize and Shadow Word: Death.

Since Thaddius' Polarity Shift is on auto-cast, Nerubian Egg will always immediately be changed into a 4/4 Nerubian and you will gain early value on the board.

To help you beat Thaddius, we created the three decks presented below. You can also get some inspiration from them to create decks for other classes.
